Gotama, I skied the Nordica Hellcat, Volkl Bridge, Dynastar Mythic Rider, Scott Punisher, Blizzard Cronus and a Head Monster 78.
A bit about me:
6'2" 225#, I can turn left, right and stop...
I've been demoing (and selling) skis for living for 15yrs.
I ski 75 to 100 days a year, mostly at Stowe Vt. w/ 2 or so trips west a year.
The demo was at Stratton Vt. conditions were very firm (might as well have been chemically hardened race course) with about 3" of superlight duff snow that was quickly pushed around on top. There was enough soft snow on the edges to get a feel for how the skis would transition from firm to soft and from soft to firm. Edge grip was put to the test. Oh, yeah...my testing partner for the day was on the USST development team at 15...she (yes SHE) rips, on alpine or tele. Taking it easy was not an option.
I liked everything I skied...up to a point.
The Nordica was skied first with the best conditions of the day. It will rail 2 footed turns but it feels a bit clunky (90mm will do that), the sidecut also felt unsettled going in and out of the softer snow. It was really fun to roll up on edge and ride the sidecut, but thats ALL it felt like it wanted to do, it didn'twant to skarve, it didn'twant to make quick edgeset changes, it wanted to get on edge early and stay there. In my opinion it's 6mm too wide for it's sidecut, the Jet Fuel makes more sense (as does the Enforcer).
The Volkl Bridge I skied next as a 'control' to test what I thought of the Hellcat. It felt really good. Way more of a freeride feel (that's what I mean by control, I wanted to see if what I think I like IS what I like). it was able to make quick edgeset short radius turns or it could be rolled over and arc'd. It didn't do anything funky going from soft to firm, it felt like it would be really good in softer snow (I skied this on true boiler plate). This will be an improvement on the Karma, you gain some soft snow performance, lose a tiny bit of hard snow performance end up with a better freeride ski. The graphics are Killer.
The Dynastar Mythic Rider was next, it replaces the 8800, a ski I've had luke warm feelings about. I liked it. It has a bit more sidecut and a bit more oomph. This ski fits my idea of a 'one ski' ski. It handled the hardest snow better than the Bridge, it carved really nice mid radius turns and it could make quick fall line turns, I'm positive I would like it in bumps also. If there was a problem it was that it still has a 'vanilla' feel to me, this is purely subjective but I wasn't wowed, I also would have prefered a longer ski. I think this will REALLY impress everyone who likes the 8800.
The Scott Punisher is a new model for next year, it's a twintip version of the Mission ($100 LESS). I was impressed. This ski has a really odd tip profile, the sidecut starts about 5cm down from the tip contact point and it has a progressive sidecut, more sidecut in the front 1/2 less in the 2nd 1/2. This was really noticable on snow. the ski pulled you into the turn but felt very easy to adjust the radius mid-turn. this is a quality that I look for in skis I personally would buy. The ski didn't have much life to it, it was damp and solid feeling with good grip. It blew through heavy/crusty snow under some snow making guns without flinching and railed on some hard snow. I'd say it felt like a cross between a K2 and a Volkl (I know, I know...)
The Blizzard Cronus (88mm) was exactly what I hoped it would be, solid edge grip (really solid) great in the softer snow, easy to make quick fall line edge changes, easy to roll over and arc. It has a nice all-mountain freeride sidecut, it will happily carve or skarve. It did everything the Mythic Rider did but I liked this feel better. The sidecut felt a little more symetrical than I like, I would prefer a bit less sidecut at turn completion (it likes to finish turns) but I could live happily with this ski.
The Head 78 was exactly like a miniature iM88. The 88 is my favorite ski...ever. It suits my style to a T, solid edge grip, lots of taper, smooth, supple and a wide platform that can be tossed around. You don't ride the sidecut you make turns. Same with the 78, just not as wide. I (heart) HEAD.
So in conclussion, these are all skis in the upper 80mm to low 90mm waisted skis. They are all arguably 'one ski' skis with a freeride flair. Here's where personal style comes into play: I wouldn't trade my iM88 for any of these, I liked all of them (and most were too short for me, a problem with demos), I would be happy to spend a day on any if my luggage got lost but I wouldn't spend my money on replacing my ski with one of these.
