This is more of a statement than a question but have you ever really considered the physics of the game? Most everyone that talks about pool laments about how the game is one of geometry.
What brings this up is that I was playing Ray Martin (His name is well worth typing into the google search engine) last night and he said he didn't study the geometry, or angles if you will, about the table when he first started playing. Rather he studied the action and reaction of the cue ball, they physics.
When Ray Martin talks, people listen, so I went home and looked something up about the subject. I highly recommend you take some time to read up on the link I provided. You'll be surprised at how intriguing it is and how much you'll want to apply the concept to your game.
