Smile Re: Modifications to FIRST Gray Wheels for Better Consistency
We used 6" FIRST wheels with a 2.5-3" squish factor. That's what our team named it, it's stuck around since week 1.

We had a similar issue with consistency on leaving the shooter. However, we improved this by funneling the balls more precisely into the shooter, not modifying the wheels. Another way you could do it with wheels if your design allows for it is making it four wheels (if it's already not.) We used two wheels and couldn't change ours but we added two pieces at the top of our turret to ensure that balls entered the wheels at the same spot since before there was a good 3-4" wiggle room that they could enter variably at.

I don't know how your shooter is designed but if there's anyway you can make the balls enter more consistently I think that will be much more helpful in improving your shooter if you have a good squish on the ball.
