I'm planning to buy a T3 soon and am hoping to get some opinions as to the differences in handling of the 3 lengths. I currently own an XP 154" that I updated to full XM chassis (flex edge, Tmo, S36, spindles and skis, post forward, etc.), so it handles very close to the pre-T3 XMs. I've never ridden a T3 though. I'm likely keeping the trusty XP, so I'm tempted to get a longer track T3 for pow days. I've read a lot of positive comments about the capability of the 174", but am not sure about the drawbacks. Anybody have significant time on the 163" and 174"? Also interested in hearing about the 154 T3. I don't care that much about straight up climbing ability, as I figure all of the T3s will be better than my current rig in that department. More interested in how they perform in the trees (e.g., do they all hold a sidehill equally well?) and the fun factor. We also have long-ish approaches to the alpine around here (WA), so I'm interested in how the different lengths perform in terms of cooling (probably buying used, and the '15s are way more abundant at this point). Thanks in advance!
