Short track and mtn phazers each have their trade-offs. Stock short tracks apparently are no good in deep powder, but are geared for 80-90mph and the fx comes with good suspension. Mtn's do well in deep pow stock but are geared for 60-65mph and have crap suspension. As a mtn lite rider, I can tell you that the 14x144 is a pretty good all around track. A magazine article said that it has slightly less footprint than a standard 15x136 and it does seem to rear steer, as well as hook up in pow, pretty darn well. So, buy short track and do track length mods, or buy mtn and then GYT shocks and a paint job. Mtn lite is definitely awesome in ditches- carves top turns on one ski while "seated" with lots of snow or almost none. It does, however, have shorter a-arms/ski-stance/suspension travel and is a bit tippier(I #*$&@/u/me).
