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, the first lacrosse head including an environmental indicator, the environmental indicator adapted to output different output corresponding to physical changes of the first material of the first lacrosse head, said physical changes corresponding to a change in at least one of flexibility and rigidity of the first lacrosse head;transforming the environmental indicator so that the environmental indicator outputs at least one of a visual and audible output to indicate a change in the at least one of flexibility and rigidity of the first lacrosse head; andchanging from the first lacrosse head to a second lacrosse head constructed from a second material different from the first material in response to the at least one of a visual and audible output;wherein the second lacrosse head is at least one of less flexible and more rigid than the first lacrosse head when the first and second lacrosse heads are subjected to a temperature above a preselected temperature. 2. The method of claim 1 wherein the environmental indicator is a temperature indicator included in the first material. 3. The method of claim 1 wherein the first lacrosse head has a first elastic modulus when subjected to the preselected temperature, and wherein the second lacrosse head has a second elastic modulus when subjected to the preselected temperature, the first elastic modulus being greater than the second elastic modulus. 4. The method of claim 1 wherein the first material is a 6,6 polyamide and the second material is a polypthalamide. 5. The method of claim 1 wherein the second head includes a temperature indicator. 6. The method of claim 1 wherein the environmental indicator includes a thermally sensitive material that is at least one of mixed with the first material and affixed to the first lacrosse head. 7. The method of claim 1 wherein the output is a visual output that is output when the temperature exceeds the preselected temperature. 8. The method of claim 1 wherein the environmental indicator is a thermochromic material included in the first lacrosse head. 9. A method of using lacrosse heads comprising: providing a first lacrosse head, a second lacrosse head, and at least one lacrosse handle, each of the first and second lacrosse heads having a different set of material properties, at least one of the first lacrosse head, the second lacrosse head and the lacrosse handle including a temperature indicator; sensing a temperature condition with the temperature indicator, the temperature condition affecting at least one of the material properties of the at least one of the first and second lacrosse heads;outputting an output with the temperature indicator in response to the sensing of the temperature condition; wherein a lacrosse player selects either the first lacrosse head or the second lacrosse head based on the output; and wherein a lacrosse player engages in a lacrosse activity with the selected first lacrosse head or the second lacrosse head. 10. The method of claim 9, 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. 11. The method of claim 10 comprising outputting the output when the temperature is above or below the first temperature. 12. The method of claim 10 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. 13. The method of claim 9 wherein, 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. 14. The method of claim 9 wherein the temperature indicator includes a thermochromic ink that changes appearance above a first temperature. 15. The method of claim 9 wherein the temperature indicator changes color when the lacrosse head is subjected to a particular temperature at which the material changes elasticity. 16. 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, at least one of the first lacrosse head and the lacrosse handle including a temperature indicator;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 an output with the temperature indicator 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 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 above an elasticity changing temperature.
