We used FP motors and followed 1771 recommendation on the nuances of the shroud shape: We could push any bot. We put our fans on a turret and varied them between 75% and 100% power in our final two matches. The fans properly used have a dramatic impact. I have no concept of how an expert driver could possibly avoid a pin unless she/he gets their alliance bot to run intentionally run interference: we were faster, more manueverable and could push stronger.

If I could start over, then I would recommend a 4 wheel drive train and at least 15 lbs of thrust from four fans on a turret. Turn it into Sumo bot wrestling. Easy pushes and excruciatingly long pins in front of alliance human shooters.

I might even throw in a compressor/tubing and solenoids to rapidly puff air to keep the traction wheels and the regolith in front of them free of dust to improve traction. Ball manipulation would be completely optional/superfluous.
