I compiled what we have so far. Anyone from Team IFI care to elaborate if one team found it first, or it was found separately.

Also, 1073, 27, 67, anyone else with the setup, care to share how you came across it?
You are missing 910. They had my favorite as they had the highest surface speed on the top roller of any of the teams I talked to. This allowed them to acquire the ball at a run while most of us had to take it at a walk. In general, on a collector, a top roller that engages a ball to the floor should have a surface speed equal to or greater than 2x the robot traveling speed. Our original top-spin roller was a 10 FPS surface speed which corresponded with our 5 FPS low gear. Our pincher was somewhere between 1-2 FPS SS. I think 910 managed a system with around 8 FPS SS on their roller.

1718 had a great pincher system as well.
