The shooter wheels are 775 Pros with 3:1 VPs
Centering rollers are Bag motors on 10:1 VPs

I'm curious if reducing the width of the shooter would make for a more reliable shot.

Our shot consistency was very high while the shooter was functional. While designing the shooter we were very mindful of centering correctly each time. The centering was very reliable. Probably +/- 1 inch of variance at worst on the centering. We had low compression with the centering wheels, a lexan guide in the center of the robot to funnel (using the natural gap in the bumpers to our advantage). The spirals inspired by 2481 were polycord wrapped in hockey tape to get maximum spiral grip, and the PVC roller was waxed to center quickly.

So summary left/right offset was never a problem. Up/down variability by far was a larger issue, and that wasn't really much of an issue either. When the transfer between the rollers was clean we would easily hit 90%+ shot accuracy. When the shooter would miss shots would be the transfer between the centering rollers to the shooter wheels. We eventually resolved this at our second event by increasing the release velocity of the centering rollers to reduce the amount of time that the ball contacted both rollers at the same time and we saw a significant improvement in reliability of up/down. (we would have extremely low shots somewhat arbitrarily)
