To help ease the impatience of waiting for our next ski trip, some retail therapy might be required! I currently ski either some Rossignol Experience 84 or some K2 Maden'AK fat skis for powder. Now, the Rossignols, being all-mountain and 84mm underfoot are great on piste, but not so good in the soft stuff because I am 100kg. The K2s are like wearing two snowboards and are very skittish on piste. The new breed of all mountain skis look like they could combine the two and save having to forecast what I might be skiing on any given day. I am looking at the Rossignol Sin 7. They are 98mm underfoot and have massive rocker but also a tight turn radius. I am thinking one pair of these will do it all. Does anyone else ski on anything similar? If so, do the 'all mountain' claims stack up?
