Pros: Variable stiffness, great at high speed
Cons: pricey, hard to find
I know these skis are exaclty like my Chip Monster 78s - Head has simply renamed the ski and continued ot market it. I have 2 pair in the 177 length and they are simply a joy for me to ski on groomers, through bumps and down the frontside bowls at Mt. Hood Meadows after they have been skied out. I found them on an open demo at Sun Valley and they were easily the best (for me) out of the 7 or so skis I tried.
The great thing about them is they are softer at slower speeds and therefore behave better in the bumps than I would have expected - not that they're a bump ski of any sort, but they are manageable... and the softer feel at slower speeds is nice for comfy carving. Meanwhile, when you want to rip them down a groomer, there is no chatter or any sense of instability whatsoever; it's like they lock up firm for you and have no speed limit. This makes them lots of fun for me inbounds going down either groomers or skied-out steeps, and helps you get through slush and crud in the spring.
This sort of fun does not come without a little compromise - they aren't light, they are 78 underfoot, so while they do OK in powder and several inches of fresh, they do require you to pay attention when you use them in these conditions (just use decent technique, you'll be fine). Plus, like (I guess) most skis that like skiing fast, you definitely know if you get a bit lazy and sit back - very stiff beaver tail at speed.
However, if you want a ski that you can rail on the groom, that does fine (when tuned) on ice and hardpack, and will behave OK in the bumps, all things considered, I think this is a really fun resort ski.
I am 6', 200-205, if that helps you evaluate what I am saying about the stiffness of the ski.
