So I have been on a 93 mm ski for the last three ski seasons. I loved the versatility of that ski, but wanted something a little fatter to better handle the skiing I love most, which is in the soft stuff out west. I was expecting to lose some performance on-piste, but was proven wrong when I used them for the first time on my local Minnesota hill. Keep in mind that the runs are short, but I was able to carve just as hard and fast as with my 93 mm skis. It held a solid edge, and the ski was incredibly quick edge to edge. I was sold after the first run, and for the first time in a while I had a blast on a Minnesota hill. I may actually go out one more time before I head to Whistler in January. Can't wait to try them in the soft stuff, but I am confident they will handle those conditions like a champ. I will update when I get to ski more variable conditions.
Definitely listen when people say "size-up." Coming from a 176 cm length ski and being 5'9" and 165 lbs, I thought the 184 could be a bit long. Turns felt effortless with that length and I would not want to ski anything shorter. If you are anywhere near my size or bigger, go 184.
Update: skied four days in Whistler and the ski performed in every condition. I won't expand, but all the other reviews sum it up well. Great ski for any condition. Still shocked by the carving ability for a 108mm ski.
