[12 piece bucket]

I probably straighten my right arm too much too soon. Needs some work. What exactly is the importance of maintaining this bend all the way to impact? Does it give more force/speed or a better angle (of approach/attack) - or what is it?

basically it's like a punch... would you rather have somebody punch you with a completely straight arm when it impacts your jaw or would you rather have them have some bend at the elbow and straighten it thru jaw . . .

So you basically want to have some accumulator left to bust the ball with . . . BUT . . . you do want it to straighten . . . don't hang on to the bend like this cat could be doing . . . for a multitude of possible reasons.
