The performance of a shaft depends on several factors -- age, weight, position, playing style, and expectation of how long you want your shaft to last. Pro lacrosse players look for the lightest shaft possible for ultimate performance with enough durability to withstand the extreme abuse. Still, they replace shafts regularly just like pro hockey players.

It's important to understand the the trade off between strength and weight. If you use the lightest shaft on the market, you will be able to shoot harder and move faster, but your shaft could easily be damaged during play. If you use the strongest shaft on the market, you may never damage your shaft during play, but your shots and motions will be significantly slower. When picking what shaft is best for you, consider those factors and make your decision based on your needs of how strong and how light you want your shaft to be.
