9mm wide GT2 (5mm) is VERY borderline for an FRC drivetrain, as it's only rated to around .8 HP at typical WCD high gear wheel rpms (1000+rpm)(with common 24T pulleys). 2 CIM gearbox can output peak ~.9HP. You would need to step up to at least 26T pulleys to meet this requirement with 9mm belts.

I don't think anyone is recommending the 3mm GT2 for primary drive train loads (they are however final for initial reduction in drives).
We've used them a good deal on intakes, shooters, initial drive reductions, etc... with great success.
