Purchased this ski in a 175cm from Village Bike and Ski in January. First time out at Bear Valley, California on them earlier this week. Packed groomers, very cold conditions for California, also steeps and dry powder bumps, crud.
The ski is definitely a race-feeling ski, very strong even flex. The dual radius system really works, took the ski from medium radius carved turns at speed up into short radius with just a little load onto the front of the ski. This ski wants to be up on edge and the carve rails were about an inch to two inches deep, very clean and again, you can alter the radius mid-turn based on which part of your foot you are emphasizing. Ski is 73 cm underfoot, if you are an expert skier, this is one very beefy, powerful, yet incredibly snappy model. It is very responsive to race-level foot, knee and hip articulations (ie entering the turn with hip, then tune with knee, then walk the ski through the turn weighting with the length of your foot). You could masters race this ski.
Second, it is excellent off-piste (unless of course you are looking for a +80 underfoot cheater rocker water ski!), but if you are a good skier, these will make you stay over your foot and then the wide tip and even flex allow for short radius carving engagement on steeps and bumps. There was some chop deep crud at lower mountain, these broke through easily (likely due to the weight of the skier, not the equipment!).
The only condition I can't speak to (yet) is really deep powder, but I don't see why they wouldn't rip there too.
What I learned from my search for new skis is that probably every manufacturer makes a good ski, you need to know who you are as a skier and what kind of turns you really make on the hill and what kind of arcs you like to make.
Glad I purchased this equipment, Village was extremely helpful, this ski is a blast and I think I only experienced about 50% of its capability, can't wait to learn its features more. At speed, with a little tail loading, it will definitely sling you off the back; properly balanced it slings itself into the next turn, easy to load and release / snap it back uphill for early edge engagement into the next arc.
Am a PSIA-W Level III, 220 lbs, 6'3". Boots are Tecnica Inferno 130, non-race model so that may help you evaluate what boot is on this ski, the flex of the boot and ski must match as well. This combo works for me. If you are able to carve a pure arc and have race or instructor level balance, this is an excellent ski to consider.
