Help me choose a new waxless backcountry ski

All other things being equal, a single camber ski should turn in soft snow better than a 1/1/2 camber ski. But all things are not equal between these skis. Also, not all single camber skis are of the same camber. As I mentioned in my prior post, the Guide/Annum I tried was very soft, a real wet noodle. Another issue is the length of the cambered section of the ski. The BC125 has a traditional camber, i.e., pretty much the full length of the ski. The Vector BC has a rockered tip and tail and a short cambered section (which, to eye, seemed nearly flat, i.e., almost no camber).

I was told by the Rossi rep, and it seems about right, that the 125 stands for 1 1/4 camber, which helps explain why they get a fair glide on the posi base.  My vote, for the OP, of the S-Bound over the BC 125 was based on the initial interpretation that trolling for turns was  a secondary consideration -  sounds like further consideration is in order.

If the very fun BC 125, a 'nordic crossover', is selected, note that the obvious binding mount reference scribe is the ski balance point, typical of nordic gear, not necessarily the pin line 'must mount' location (pin line on balance point is fine for some aspects of touring, but may be less than ideal for turns depending on style - I would mount pinline 1-2 cm forward, especially if it's about the down..).  No constructive comments to offer in this regard for the S-Bound..

While everything is on sale now, I know the dollars add up, but if touring for miles is in the cards, then investment in a free pivot binding will save lots of energy (for the down and climb back   )   The Rossi is definitely a candidate for something like a Switchback.  The S-bound I'd be more inclined to stay with pin and cable (or hardwire).

I've seen a bit of dicussion on the Internet re the BC125 mounting point. It appears to be standard shape ski sidecut and traditional camber pattern. If so, I'd probably mount it center-of-ball-of-foot-on-center-of-running-surface. That's how I mounted my most recent 4 or 5 pairs of tele boards and they turned much better (quicker turn initiation) than the pins on chord center. Is there a factory boot center line on the BC125?

Question for those on BC125: I've heard that the base is extruded p-tex that will not accept glide wax. Is that true?

davidG and others, do you think the T4 is enough boot to turn the BC125 or Vector BC?

Steve, good point about the boot..  T4 for the Rossi? yeah, but just  -  I'll meadowskip the BC125 with Excursions, including laps, but also boot up with T1s for resort and sidecountry - much fun.   For the Vector BC, no way is T4 enough boot... 

About the BC125 base, I don't know, but I hotwax it as needed and seems to be receptive.  And it's considerably faster on low angle glides than the Vector BC.

Agree with BOF on CRS, but hey, it's about the turns..   

I purchased a pair of Rossi 125 and have used them early season around Revelstoke and Rogers Pass, and on Saphire Col during the most recent dry spell. I have them mounted with onyx bindings which i'm sure will bring some chuckles. Skis like most touring 90 underfoot traditional skis. The flex isn't as progressive as other touring skis but for 200$ I can overlook it. Fun ski to have during long flat approaches (a-slog-in valley). Stoked to use them around the cascades come spring time. When there is pow to be had though I of course use drifters
