Me and my friends enjoy Golden Tee, so that is something that is considered untouchable for me.
I get it, I really do cause I did it.
My first panel was a monster:
2-8way Joy, 8 buttons each + p1, p2, p1 coin, p2 coin, trackball w/ 2 buttons, dedicated 4way ball-top & admin buttons.
My current:
1-Servostick, 2 buttons + p1, p2, (+ p1 coin, p2 coin, pause and exit are hidden off the panel)
And all the extra crap from the first is in a box somewhere, lol
For Golden Tee you need so much room around the ball to smack it. I would want 9" minimum between the ball and P2 and about the same to the bezel. If you have the space for a second cab build a dedicated machine for trackball games.. Golden Tees are up on craigslist constantly here in FL, sometimes really cheap if they aren't working. I would buy one if they weren't like 6' deep.
