A first lacrosse head constructed from a first material having first properties or a second lacrosse head constructed from a second material having second properties is selectively used in lacrosse activities, based on environmental conditions, such as temperature, humidity and/or solar activity, to provide generally consistent head performance as perceived by a lacrosse player across a range of environmental conditions. The first and second heads can be identical in structure, but constructed from different materials. For example, the first head can include a polyamide, optionally, Nylon 6,6 polyamide, and the second head can include a high performance polyamide resin, optionally a polypthalamide. An environmental indicator that provides visual and/or audible output with regard to environmental conditions can be included with at least one of the first head, the second head and a shaft to which the heads can be joined. Related methods of use are also provided.

1. A method of selecting between different lacrosse heads comprising: providing a first lacrosse head constructed from a first material having an elasticity, the first lacrosse head joined with a lacrosse handle, and a temperature indicator joined with at least one of the first lacrosse head and the lacrosse handle, the temperature indicator adapted to output a first temperature-related output and a second temperature-related output, the second temperature-related output based on an elasticity changing temperature that corresponds to a change in the elasticity of the first material of the first lacrosse head;transforming the temperature indicator so that the temperature indicator transitions from outputting the first temperature-related output to outputting the second temperature-related output; andchanging from the first lacrosse head to a second lacrosse head constructed from a second material in response to the second temperature-related output corresponding to the change in elasticity of the first material of the first lacrosse head;wherein the second lacrosse head has a second elasticity less than said first elasticity,whereby the second lacrosse head functions better than the first lacrosse head when subjected to temperatures above the elasticity changing temperature. 2. The method of claim 1 wherein the temperature indicator includes a thermally sensitive material. 3. The method of claim 2 wherein the thermally sensitive material is at least one of mixed with the first material and affixed to the first lacrosse head. 4. The method of claim 1 wherein the first lacrosse head has a first elastic modulus when subjected to the elasticity changing temperature indicated by the second temperature-related output provided in said providing step, and wherein the second lacrosse head has a second elastic modulus when subjected to the elasticity changing temperature indicated by the second temperature-related output provided in said providing step, the first elastic modulus being greater than the second elastic modulus. 5. The method of claim 1 wherein the first material is a 6,6 polyamide and the second lacrosse head is constructed from a second material, the second material being a polypthalamide. 6. The method of claim 1 wherein the second head includes a temperature indicator. 7. The method of claim 1 wherein the temperature indicator generates a first visual output when the temperature is within a first temperature range, and a second visual output when the temperature is within a second temperature range, wherein the second temperature range is greater than the first temperature range. 8. The method of claim 1 wherein the second temperature-related output is a visual output that is output when the temperature exceeds the elasticity changing temperature. 9. The method of claim 1 wherein the second temperature-related output is a visual output that is output when the temperature is below the elasticity changing temperature. 10. A method of using lacrosse heads comprising: providing a first lacrosse head and a second lacrosse head, each of the first and second lacrosse heads having a different set of material properties,providing at least one lacrosse handle,providing an environmental indicator joined with at least one of the first lacrosse head, the second lacrosse head and the lacrosse handle;sensing an environmental condition with the environmental indicator;outputting with the environmental indicator at least one of a visual and audible output in response to the sensing of the environmental condition;wherein a lacrosse player selects either the first lacrosse head or the second lacrosse head based on the at least one of the visual and audible output; andwherein a lacrosse player engages in a lacrosse activity with the selected first lacrosse head or the second lacrosse head. 11. The method of claim 10, wherein the environmental condition is temperature, wherein the selecting step includes selecting the first lacrosse head when the temperature is below a first temperature and selecting the second lacrosse head when the temperature is above the first temperature,whereby a lacrosse player changes from the first lacrosse head to the second lacrosse head above the first temperature without being affected by a change in performance characteristics of the first lacrosse head, as would be the case if the lacrosse player continued to use the first lacrosse head constructed from the first material at temperatures above the first temperature. 12. The method of claim 11 comprising outputting the visual output when the temperature is above or below the first temperature. 13. The method of claim 11 wherein the first temperature is at least one of 80° F., 85° F., 90° F., 95° F., 100° F., 105° F., 110° F., 115° F. and 120° F. 14. The method of claim 10, wherein the environmental condition is humidity,wherein the selecting step includes selecting the first head when the humidity is below a first humidity and selecting the second head when the humidity is above the first humidity,whereby a lacrosse player changes from the first lacrosse head to the second lacrosse head above the first humidity without being affected by a change in performance of the first lacrosse head, as would be the case if the lacrosse player continued to use the first lacrosse head constructed from the first material at humidity levels above the first humidity. 15. The method of claim 14 comprising outputting the visual output when the humidity is above or below the first humidity. 16. The method of claim 14 wherein the first humidity is at least one of 50%, 60%, 70%, 80%, 90% and 100% humidity. 17. The method of claim 10 wherein the environmental indicator includes a thermochromic ink that changes appearance above a first temperature. 18. The method of claim 10 wherein the environmental indicator changes color when the lacrosse head is subjected to a particular temperature at which the material changes elasticity. 19. The method of claim 10 wherein the environmental condition is temperature, wherein the second material has second performance characteristics when the second material is above a first temperature, which second performance characteristics mimic first performance characteristics of the first material when the first material is below the first temperature. 20. A method of using lacrosse equipment: providing a first lacrosse head constructed from a first material having an elasticity, the first lacrosse head joined with a lacrosse handle, the first lacrosse head including a scoop joined with sidewalls and a base, with a temperature indicator joined with at least one of the first lacrosse head and the lacrosse handle;sensing with the temperature indicator at least one of a temperature and a change in the temperature, indicative of a change in the elasticity of the first material from which the first lacrosse head is constructed; andoutputting with the temperature indicator a visual output in response to the sensing of the temperature to alert a lacrosse player to the change in elasticity of the first material from which the first lacrosse head is constructed,wherein the lacrosse player is prompted to select a different, second lacrosse head in response to the visual output so that the lacrosse player can engage in a lacrosse activity with the second lacrosse head,wherein the second lacrosse head is constructed from a second material that is less elastic than the first material of the first lacrosse head after the elasticity of the first material from which the first lacrosse head is constructed changes.
