I have been trying to work on my jump shots lately and I've been noticing that several players in my league use different techniques. I have figured out that the way I feel most comfortable jumping is with my hand in front of my shoulder, or "spear chucking" as I've heard it called, as opposed to hand behing my body and jacking up to hit the ball. Now I'm wondering if it's best to use chalk or not as I have seen people do both. Is there a way that works best or is this also just mainly a comfort thing??
