ok, ill be the odd man out.
I was wrenching on an MF2 the other day actually... its a pretty snazzy ride. I took it for a quick spin around the parking lot and it handled really well. some time ago when they first came out i got some wheel time with one on the dirt and I have to say it was a pretty impressive little truck. good response, smooth feel, consistant handling.
on the other hand i was no where near trading in my T4 for one. Im consistantly faster with my T4 (and on the track ive probably had more wheel time with the mf2) and in my opinion its a little bit easier to find the suspension sweet spot on the t4. also, ive never broken anything on my t4 or gt without doing somthing really dumb with it. Im an AE guy
