Well, if it comes down to it:
same crap but endorsed by "top pros"
The way I see it, if your using the gun, your hand is covering it. Who's going to stop a game to laugh at your grip tape? The only time someone really has a chance to see it is laying on a table in the staging area. And if someone is so hung up on it they actually start trying to give you a hard time, use the distraction to toss a quarter in their hopper. If looks are really that essential to winning, cross wrap it fancy style like a samurai sword with color coordinated tape.
What it comes down to is, make some grips. Buy some grips. Get ghetto with it. Whatever it takes to play comfortably because if the gun doesn't feel right it will affect your play.
