Pros: Lively w/ lots of pop out of turns, and very stable.
Cons: need more days on these to really say...
Me: 5'8" / 160lb male.
Caveat: I just picked these up in an end of season deal that was too good to pass up here (thanks Scott!!!), and have limited time on them, so I can't comment on mogul performance (didn't really have to deal w/ moguls), boilerplate ice or powder/deep soft snow performance since those conditions were absent. I'll add more to this as I get more days on these in various conditions, including a few more stars for durability.
Conditions: perfect warm spring temps, skiing off-piste packed powder on upper Mammoth mountain about 5 days after our last storm, with wetter spring snow on mid & lower mountain; skied mostly off-piste runs, w/ groomers as needed to get back to lifts.
Initial Impression: After reading dawg's reviews here, I was a little worred that I might be too light to really work this ski effectively. But after skiing them, I just wanted to say that these are not super-stiff skis that require a much heavier skier to get the most out of them. I've skied my Elan 1010s all season (183cm), and these have considerably more energy and pop exiting turns, and feel much quicker overall (as any narrower, front-side oriented ski would). Despite the relatively quick and nimble feel, these were super stable off-piste and on highspeed groomers, and were rock solid with no real discernable tip deflection through the spring crud (which was definitely not the hard re-frozen chopped up variety of crud).
Comparisons: I demo'd Volkl AC50's (177cm or 178cm) 2 seasons ago, and found the AC50's to be extremely stable skis on highspeed groomers and rock solid in offpiste spring crud, but they were too stiff to really work well for my weight. They owned me, and I doubt I would have been able to generate much flex in deep light snow. As a relative lightweight, the AC50 in the 170cm-ish version probably would have been a better choice for me (but was unavailable to demo at the time).
The frontside skis I had for the past 2 seasons were 170cm Nordica Jet Fuels (the version w/ 2 sheets metal, as opposed to the 2010 Jet Fuel CA that had no metal and was simply the 2010 name for the Afterburner from prior seasons). I found the Jet Fuels to be an extremely versatile frontside 50/50 (or maybe 60/40 onpiste/offpiste) ski that had a similar unshakeable stability that the AC50's had, but with a softer flex pattern that was much better suited to my body weight.
The 82XTI's have that same feeling of stabilty as the Jet Fuel Ti, but feel livelier overall with a little more rebound energy when exiting turns. I sold my Jet Fuels at the end of last season (in an effort to pare it down to a 2-ski quiver), so I can't make a same-day, run-by-run direct comparison between the Jet Fuels the 82XTI's, but I'd estimate the 82XTI's to be a touch softer longitudinally, with at least as good if not better torsional/lateral stiffness as the Jet Fuel Ti. So yeah, I've drunk Elan's "waveflex" kool-aid, and haven't keeled over yet.
Overall, I'm really happy with the 82XTI's as replacements for my Jet Fuels as my go-to front-side skis for anything less than a foot of fresh.
