Calibrating the victors isn't the hard part... the joysticks would still read something other than 127 when centered, and that has to be compensated for.

Some trimmer pots connected to the OI and a few extra lines of code could compensate for drift in the joysticks and a toggle switch doesn't drift since it is either on, or not with nothing in between.
Adding in trimmer pots would be adding complexity mechanically/electrically, something I'm not inclined to do (it's something else to fall apart/get bumped on the OI). Also, a trimmer pot wouldn't be able to scale the joystick's input -- although the center would be at 127, the endpoints wouldn't be at 0 and 254 (I believe 0 to 254 is correct, although the exact values are unimportant for the point I'm trying to make).

What would the toggle switch be used for?
