22 wet weather setup - is rear motor the only real option

[Legacy555]

Ran my 22 on wet grass at the weekend and got truly whipped!
Tried loads of things and added 70g of weight over the gearbox, but it was still really crap.

I'm starting to think that rear motor is the only option in those circumstances but I was beaten by a Cougar SV??? that looked good.... maybe becuase its motor is so much closer to the rear axle than the 22.

Has anyone found a good wet setup for the mid-motor 22 on wet grass/asto???
