I think this is one of the most underrated aspects to how well one can stroke the cueball. It's pretty amazing, for the longest time I had adapted an off-balance stance, and was shooting bad, but thought all along it was my stroke. Well, it was my stroke, but what was causing my stroke to be crooked was my balance. I made a minor adjustment in my stance, and suddenly I am comfortable and stroking straight. I focused a long time on the grip, alignment, etc., but have found that that has all come natural to me again when I am comfortable, rock solid, and balanced. Today was the first time I ran a rack of 15-ball rotation with ball in hand on the one for about 6 months.
