I'm confused. You say that 90% of her skiing is on a small bumpy ski hill in NY with too much grooming. Then you say the shop is recommending a 96 mm rockered ski and the 90 mm Line Prophet. Is she the typical Scrambler 6 graduate (i.e. grade 1), or is she more of an old-school mid-performance skier who tried the scramlber 6 and didn't like it (College graduate who got stuck in grade 1 for reason's beyond her control)?
Let's give the shop owner the benefit of the doubt, and assume he has her ability correct. It sounds like he is selling her a ski for 10% of here skiing, the trip out west. Unless small bumpy overgroomed resorts are very different in NY than they are here, I think she should get something more like a Dynastar Exclusive Active and rent the Flite or S3 when she goes out west. It would also a better ski on which to improve skills.
Ghost - unfortunately the owner at the shop didn't instill a lot of confidence.
I'm not sure what you mean by Grade 1. I think maybe I've under described her skills / ability -- I tend to do that with myself as well.
She is quite a capable skier, solidly in the high intermediate range, and can step up her game when she's feeling confident. So for example, at Steamboat she skis well on trails like Storm Peak North and South, does decent on The Edge (but a little hesitant), but got nervous in the Shadows and Closet -- and bailed out before the very bottom of those. At Alta a couple years ago she handled a few runs down Catherine's area with confidence, good speed...also was capable (and comfortable) on much of the stuff off the Collins lift. She took an intermediate class at Alta and she should have been moved up to something higher. On our first visit to Jay Peak last year she was comforatable and happy on runs like JFK, Everglade, Canyon Land...the upper part of Power Line got her nervous because of some exposed ice and rocks. At Stowe, where we've unfortuantely never had great conditions, she's mostly avoided the harder runs, but was ok on things like Centerlline and Hayride when the conditions were softish, loved the glades on skier right of Nosedive, reluctantly survived Chin Clip on an day that seemed like it would be soft but was bumped up and icy. Winter Park - loved the glades off of Perry's Peak, did well on Drunken Frenchman, Gambler, Aces and Eights, and got in over her head on got a little freaked out on upper part of Thunderbird skiing in some wind packed powder.
So - if you're familiar with those places and runs, to summarize she skis really well (skis the terrain/line, doesnt' have to skid to slow, looks for small kickers to get air, has good speed) on almost any intermediate run anywhere, hates icy conditions, is pretty comfortable in glades but gets a little nervous on steep runs where she can see WAY down the hill. One thing that's kind of funny is that she's not afraid of hitting some decent sized jumps in the terrain parks.
FWIW, the S3 we were looking at said 92mm underfoot on it. Not sure why, but that's what the ski said. I held it up to the Flite and it didn't seem 6mm wider so I'd tend to believe the 92.
The reason I think the Flite would work well for her is that she wants a one-ski do all ski, she likes to be off-piste as much as we can, and I feel that what's holding her back the most is only confidence. My experience moving to a wider ski was that I suddenly had this great stable platform from which to work...if that makes any sense. I was able to start pushing my personal limits of how and where I skied because I always felt like I coudl get back to center and get stable when I needed to. Crud that I used to avoid becuase my skis would hook up became fun as I either plowed or carved through it, or looked for piled up snow to get a little air. Knowing how she skis, I think she would feel the same.
I'll take a look at the Dynastar's you mentioned. If we still leaned toward the Flite, what would be your thoughts on size for her?
