yes the rev and the xp both, have buddies who ride them and we'll switch back and fourth. can carve and sidehill well on both the rev and the xp but i'm a rolly polly kind of rider and the balance point on the doo chassis has always seemed like a ragged edge to me. takes a lot more effort for me to do the same manuvers on the doo as on a M or poo.
What about the IQ RAW chassis? I'm guessing closer to your M.
