okay i got it down to two
let me know!?
It sounds like you want the Seths, get em!!! I'd totally get them if I were you. They're really not that fat, and like someone said above, it'll be perfectly fine on hardpack. I really wouldn't worry about what that shop guy told you, these sound like the perfect skis for what youre looking for.
Arv's would be good too.
I don't think you'd be nearly as happy on blends.
I think the Blends would work great. Prophet 90s maybe too, but I think if you do ski park sometimes the Blend would work better for that and would still be great all mountain and in powder, because I'm pretty sure they are around teh same width of teh prophet 90s
