I have a 136 m10 in my warrior. To me, the transfer didn't seem that bad. At least not nearly as bad as everyone made it out to be. I could lift the skiis from a dead stop with no problem. The only place I noticed it was a lack of 'snap' coming over some bumps. This was at the end of last season though, and it may have just been me getting used to it.
Since the end of last season, I've added the heavy rear spring and a supercharger to my sled. I am hoping to try everything out soon. I do have the m10 set with quite a bit of bias on the front. (the rear wheels sit up a bit when the front touches the ground).
I suppose it all comes down to what you are looking to do. The m10 has proven itself great for the trail. If you're looking for transfer for more of a racing application, check out the expert x. You can also increase transfer by shaving the rear slide blocks or buying different ones.
I know Powerhaulic had a 136 m10 in his bender turbo, try sending him a pm.
