What is claimed is: 1. A golf ball comprising: a core; and a cover layer; wherein the golf ball has a weight of about 1.39 oz to about 1.62 oz, and at a Reynolds number of about 184,000 and a non-dimensional spin ratio of about 0.106, the golf ball has a lift-to-weight ratio of greater than about 1
What is claimed is: 1. A golf ball comprising: a core; and a cover layer; wherein the golf ball has a weight of about 1.39 oz to about 1.62 oz, and at a Reynolds number of about 184,000 and a non-dimensional spin ratio of about 0.106, the golf ball has a lift-to-weight ratio of greater than about 1.4 and a drag-to-weight ratio of greater than about 2.0. 2. The golf ball of claim 1, wherein the core comprises polybutadiene, butyl rubber, a co-reaction agent, or a peroxide. 3. The golf ball of claim 2, wherein the butyl rubber is halogenated. 4. The golf ball of claim 1, wherein the golf ball has a coefficient of restitution of about 0.550 to 0.785. 5. The golf ball of claim 4, wherein the coefficient of restitution is about 0.600 to 0.780. 6. The golf ball of claim 1, wherein the weight is about 1.45 oz to about 1.60 oz. 7. The golf ball of claim 6, wherein the weight is about 1.45 oz to about 1.58 oz. 8. The golf ball of claim 1, wherein the golf ball has an outer diameter of about 1.675 in about to 1.695 in. 9. The golf ball of claim 1, wherein the dimple coverage is 55% to 75%. 10. The golf ball of claim 1, wherein the cover layer comprises an ionomer, non-ionomer, or polyurethane. 11. The golf ball of claim 1, wherein the golf ball comprises a casing or inner cover layer disposed between the core and the cover. 12. The golf ball of claim 11, wherein the inner cover or casing layer comprises an ionomer and the cover comprises a polyurethane. 13. The golf ball of claim 1, wherein the core comprises a polybutadiene, a co-reaction agent, a peroxide, and at least one of a butyl rubber, a halogenated butyl rubber, a butyl rubber copolymer, a sulfonated butyl rubber, a polyisobutylene, an ethylene propylene diene monomer rubber, a copolymer of isobutylene and methylstyrene, or a styrene butadiene rubber. 14. The golf ball of claim 1, wherein the cover layer comprises a urethane.
