Yea I was bending the crap out of the Z10, but I like that I can do that.
I agree though, I had a gut feeling that they would perform poorly on a truly hard surface.
Mostly I just like them because they were really all-round, handled bumps very easily due to their softness, handled all kinds of turn shapes, going pretty darn fast and had plenty of forgiveness. I could feather the edges to do ski instructor demos at slow speed, roundly.
Not an all out performer, more of a good instructor ski that can rip pretty well on typical average conditions.
Thanks for the feedback about the progressor. Maybe its not worth trying after all. I definitely still want to try the Stockli Laser Cross Pro though.
There are a few front side carvers out there like the 4x4, the Nordica and a few others, perhaps the K2 you mention, that people have been talking to me about as having better edge grip. What I have experience in the past is that often times those skis that can carve like glue are difficult to smear the edges. Now if I want to arc pure carves down a nice hard surface all day long, that's great, having a ski like that is a lot of fun. However, in the bumps, not so great. While teaching a class, not so great. Etc.. They tend to be one trick pony skis IMHO, some of them. That is how I felt about the Dynastar Contact a few years back and I probably would feel that way about the 4x4 too. Based on other feedback I've gotten, some of the others mentioned are also similar like that. Lots of fun to carve, but if you truly want to cruise all mountain and make non-carved turns in certain situations, perform slow instructor demos, hit the bumps, etc...then they tend to have draw backs.
If I wanted a pure carving ski, I would probably get more of a race ski anyway. What I want is a ski that leans toward being a carving ski, but its a bit more forgiving in nature in order to handle a variety of situations in a 14-15m radius. And due to my back, probably something that is not too snappy for this year, though my back is getting stronger every week...so....may not be that much of an issue afterall.
One of the guys at the shop told me he thought the Progressor was above the Z10 in terms of performance, so that's what I was going on. If you think otherwise, I probably won't waste time and money trying it.
