I have ski'd 5 times now on my new 184cm Vices (Look Pivot 14 mounted -2cm) since I got them a week ago. I ski only east coast where you get icey hardpack groomers that turn into cut up bumpy runs and slushy crud in the afternoon. Our parks are about the same with ice, crud, and slush leading into the jump lines. I would give the ski about a 6/10 for overall stiffness. Tips are very soft and flexible and have a good amount of rocker, stiff camber underfoot, and a medium-stiff tail with a tad bit of rocker. Check out www.Backcountryfreeskier.com for a side profile shot of the rocker. The skis is AMAZINGLY PLAYFUL and FUN. I am 180lbs so it may be a bit more buttery for me than most. Turn initiation is amazing and you can make any shape turn for a radius of 21m. So easy to turn in and even easier to pull the tails up out of a carve. The rocker helps make this ski very fun and surfy. The sintered base is very quick and I have no problem getting the speed I need anywhere on the mountain. Flotation you can forget about with a waist of 83 but that's not necessary for a true park ski or anyone on the east coast. The rocker and medium stiffness makes bumps manageable for a twin but it still stays stable at speed and the edges definitely hold a carve nicely. If you run into major Ice your out of luck but that will happen on any true twin. For jibbing and rails don't let anyone tell you different as they are one of the best skis out there. Jumps are great too as long as you don't go super duper big (get a full camber stiffer twin) if you are looking to bomb 50+ footers. The are pretty forgiving and the tails have saved me many times landing backseat. Durability is top notch. Sandwhich construction, rockwell edges, race base, amazing graphic both top and bottom. Get many compliments on the mountain. Honestly the only downside I can mention about these skis are stability at 50+ mph and edge bite on steeper chutes and when you are really hauling ass and straight lining. The skis are very very very very light and get pushed around a good bit when you get into the chop. But you have to be honest with yourself. If you want a GS ski buy a real one as no twin is going to have that freight train stability and bite. I say go for the VICE man you wont regret it. Just make sure you chamfer (sand) down the edges of your top sheets before you ski them to resist chipping. Not that the top sheets are not durable but they definitely have a 90 degree edge that meets the sidewall which makes it easy to chip if you hit your skis together a lot. Wouldn't want to ruin such a nice top sheet graphic. If you need any other help on the vice just PM me as I know there is not much reviews out there.
