Got my new 2013 Prophet 90's (186) about 10 days ago and have had them out three times so far.
For the last 7 years I've been on K2 Public Enemy in 179 length.
I liked the PE's a lot. I really love the Prophets based on the three days I've been on them. Compared to the PE's they are much livelier. Short radius turns are snappy and energetic, with the ski popping out of the turn. I've also found I have to be more centered in my stance on the Prophets, rather than pressuring the front of the ski more like I did on my PEs.
I'm not goign to claim to be a great bump skier, but I do enjoy them unless they're icy. But so far I've had kind of hard time with these skis in bumps. I'm not even sure how to describe the difficulty - I just seem to find them cumbersome, find myself feeling like I"m going to trip over my own feet. Maybe it's that the PE's were easier to just slip/slide without an edge wanting to carve, whereas the Prophets seem to want to carve as soon as they're on edge?
I think the Prophets are stiffer too - and seem to rebound with more energy like I said.
Any thoughts? Should I be changing my approach at all (I'm not a zipperline skier, but pretty flowing in the bumps, trying to not be in the troughs as I find my line down)? Do I just need time to get used to the new skis and the way they feel?
