Re: Catch and shoot or off the dribble?
I always find it easier to do a pump then one dribble pull-up. It gets difficult to square up whenever you are going side to side but if you keep your dribble efficient and on a straight line it shouldn't be too difficult.
Also, you can learn to be in rythmn on a catch and shoot jumper. Give yourself a foot or so to step into the shot in order to keep a ryhtmn.
