Go for the Pro. I've got the circuit board in the back plate, between my shoulder blades and then route the 3 cables down my left arm into my glove. The micro switches are then sewn to the fingers of a cotton glove which I wear inside my trooper glove.
I then have a blaster sound, 'call to disturbance at Mos Eisley cantina' message and 'Disturbance at moisture Farm' message, which I can activate by pressing finger and thumb together or finger against blaster barrel to trip the Micro switches. Whole new level of fun
