Brushless Revo 3.3 Gearing

[fastbaja5b]

Hey guys, decided to resurrect my BL Revo conversion (bought it back off a mate)

Am planning to run it with this motor

And a Hobbywing 80A ESC on 4S A123 while retaining the 2 speed and having mechanical brakes and Tekno Electri-Clutch

I have a 15/36 gearing on it now, but I have a clutchbell that looks to be identical to a Traxxas style around 21-22 t

Would that gearing be ok or am I better suited to the 15? Internal gears are the "normal" version as fitted to the Stock Revo 2.5.
