I have read lots of books on different practice techniques. I have been shown numerous drills. I have limited time, so I normally focus on stroke practice and whatever shots gave me the most trouble. However, some days I play decent, other days I can miss ball in hand for a duck shot. Ussually when trying to get position and missing. But the position is great, LOL. So limited time, no home pool table, long work hours. Just do basic drills? set up 3 or 4 balls and practice making balls and getting position? Full length straight in shots?
