So for the past few two days I went to this pool hall and played 8 hours each day straight. The owner of the pool hall came over and gave me a few pointers and stuff but he said my biggest weakness is my ball-pocketing skills, and that's something I totally agreed with. Too many times I would miss on easy shots, and sometimes even when i get a ball in hand. Currently I've been trying to use the ghost ball method, but I can't always visualize this ghost ball all the time, making it kind of hard to know where I need to hit. Does anybody have any suggestions on any drills I should try to do, or a new different system I should try to use? I'm also confused about my bridge length and stroking style, but I'll try to figure that part on my own (currently the bridge length is a tad bit too long and my stroking style has a lot of arm movements).
