Alright guys, already deciced on ball top T stick-pluses and was thinking of going with one of Andy's track balls and a Opti-Pac. Any other opinions out there? Is it neccesarry for a 3'' track ball or will a 2 1/4 ball be sufficient? I'm not really into having a totally authentic controls and will be only playing golf, bowling, centipide, marble maddness ect.. on it? I do like a translucent ball but with finding a light and power source seems like a lot of trouble.
