You say you're really a good player and great at the shots you listed, but what you WOULD be is a road player's or better players dream come true. Most who play this game have an over inflated view of the strength of their game. In other posts you say that you have quite a bit of trouble with long straight in shots, hitting too hard, and unexplained weird caroms with the CB. That's not a sign of a "good" player.
Do you know what a good player is? It's someone that can run rack after rack and just dominate anyone of lesser skills, as well as equal skills. It's someone that makes you think that a prank was pulled on you by painting your seat with crazy glue because your ass never comes up off of it to shoot. And when you do, you're just trying to get yourself out of jail and not foul. It's also YOU having the ability to do just what I said.
I'm not quite sure you know how "bad" you really are, but it sounds like you have a lonnnnng way to go. This may be blunt, OK it IS blunt, but sometimes that slap in the face might end up doing you more good than someone agreeing with you. BTW...you're real good in 3-ball combinations? Do you know how often a "good" player has that actually come up or would be willing to chance it unless it was lined up like a laser beam? Keep practicing and working at it...that's all I can say.
