I was just wondering how much more stiff the Atomic LT and ST are compared to the Fischer Progressor 8
There are a lot of stiffer skis than the Progressor 8 but it's not a ski I would say is soft or overly forgiving. It sounds like you should demo a few skis. There are tons of skis with turning radii between 12-17 that would be a good learing tool for you. I don't know if the Progressor 8 would be that ski right now. It will skid and soft egde but not as easily as some other skis in this category. They are at home when you tip them on edge and try not to force them around. You could probably 'ski' it but it would be stiff enough that you would probably have to push it around a lot and this would not only make you a bit tired but would likely interfere with learning. Is there an area near you that has a demo day coming up? There are lots of skis out there that could suit you well. You might even look at the Progressor 7. You can find really good deals on that from last season.
