Hi all, first time post but longtime lurker. I picked up a bare X-arcade demo cabinet that Fry's was closing out for $99, and hoping to transform it into a sweet looking system. Plan to start ordering components once a certain 49-way product is finished by someone who shall remain nameless.

Anyhow, my plan is a SFII + trackball layout and I was thinking about mounting a TurboTwist 2 between and below the joystick and buttons. Kinda where people put their P1 7th button but lower so my thumb won't bump it and the steering wheel attachment clears the joystick when used.
I did some searches, but only found one person doing this which surprises me because it seems like a good position. Your hands are on either side and twister games are usually too intense to need a wrist rest. Am I missing something?
Also, I really want symmetry in my CP, so I was hoping to buy an identical TT2 knob and mount a volumne control in the corresponding P2 position. Anyone have any opinions on this whole scheme?
