Hey Steve,
I am a huge fan and follower of Harold PMTS...tipping, counter, floating between turns, O frame type skiing all as my primary ski style. This means skiing with your feet fairly close together with a very quiet cenetered upper body and the? use of upper and lower body separation. Using one foot skiing on the hard pack and firm snow adding in 2 feet in crud, powder, and the soft edge turns.
I found the RX8's to do the work for me in the the crud and bumps. There certainly are more radical sidecuts out there. I feel the dimensions on this ski make it very user friendly.
As another tool in my ski skills, I understand the soft edge and took an all day clinic with the ski doc..John Clendenin in Aspen this year and really enjoyed learning more about the soft edge.
Used his techniuqe efficiently with the RX8's. You can ski these skis flat in the bumps and crud using the soft edge or the uphill edge of the uphill ski.
Interesting, I bought my RX8's without a demo and have not looked back. I'm 155lbs level 8-9 skier and find this ski to be my favorite all time ski to date. I have a friend who is a strong level 6 skier, big guy, 240lbs that jumps around on his using lord knows what ski technique, but he loves them.
What I can tell you is that if you have the capability to ski on one ski at some point in your turns really putting the ski on edge and commtting to it...you will be treated to a supurb experience of confidence the ski hands out. It's rock solid on edge.
Having said that, if you're not quite there or don't expect to be, it's still a ski that is very user friendly capable of handling different ski techniques as well as different snow conditions exceptionally well.
Hope this helps,
Gary
