Obviously 60 for west coast cantilever drive (however the chassis is a little modified from the original design). (Poofs/RAWC just do it very well, but 60 started it)
330 probably for their 2 staged geared fisher price single jointed arm
Pneumatics are totally 254's past. I think I know your design, no offense, because I know you grew up in SoCal and how much you like the west coast styles... but who doesn't
Just a small question though, how the heck are the sides going to get bumpers? Standoffs? because I wouldnt know what team thats from as 254/968 make little posts between the wheels I believe.
