So, the wheel and paddle works great if the ball is close to the center of the ramp, not so good if it's to the side - it tends to bind up. We added additional wheels to either side (total of 3) and moved the ball sensor farther inboard (which actuates the paddle), and so far that seems to resolve the problem. Actually broke the joint at the top of the paddle a few times coming up with a fix - that van door motor has tons of torque - but we just kept drilling and replacing rivets until we had a fix, then we bolted it together.
