We initially used a VP for our shooter wheels with a 3:1 single stage and a Vex 775pro input. I wasn't there but the team reports that the gearbox didn't seem happy running at those high speeds and we had higher current draw and lower speeds than we wanted, so we switched to a CIM-ile and live seems to be much much better. Note we also did a few other things that helped the shooter draw less current (mainly taped over the spokes of the wheels so that we weren't losing as much energy moving air around) but that is our experience.

YMMV.
