rockers. is it really NECESSARY to go 10cm longer?

post #1 of 11
Thread Starter 
i usually like skis somewhere in the 174 +/- 5cm range. i cant get my mind around the giant but beautiful well reviewed 188 to 193 length skis.
do i need these? can i have fun on a 179 obsethed mini-rocker? why is that too short?
can i turn these freighters? of course, i didnt even think about that when i had 205cm straights.but they look huge now.
of course,demo. anyplace at south tahoe that demos praxis/dps/bro/ehp/s7/etc.?

In general, your deep snow ski whether conventional or not, should be longer than your daily driver. It doesn't have to be of course, but they will work better for their intended purpose if they are. Almost regardless of the circumstances, you will get thrown around more in deep 3-d snow that you will on groomers. You ideally want more fore-aft platform for the deep stuff. Heck, on groomers you can keep your balance nicely on quite short skis but for the deep snow where these skis excel, the length is on balance, an advantage.

Edited to add......Naturally, a stiff big ski can be a handful unless you ski fast enough to flex it. However, it's no problem to find a big ski that will come around nicely at moderate speeds. Choose a flex commensurate with your ability and tolerance for speed in deep snow.

Generally you'll want to go longer. How much depends on the design. With an Obsethed it just won't matter that much as the rocker is minimal. With skis like Praxis Powders, Pontoons, DP138s, Kuros, etc. - maybe 15-20 longer than typical current skis. With Hell Bents, K2's goofy sizing gets you half way there just because the sizes understate the real size by maybe 5cm (eg. a 179 Hell Bent is virtually the same length as a 185 EP Pro). The more hybridy skis, likely somewhere in between - depending on the specific design...

The short version: Yes, go longer. Exactly how much longer depends on your size & style, the specific ski in question & your intended use of the ski. In general, the answer will be between 5 and 20cm.

One of the rags had a McConkey blurb that summarized this stuff a couple of months ago. I can't find it right now, but the stuff above is compatible...

Would boldface SJ's edit. Yes, go longer for all the reasons cited. But if you get a board you can't bend below 40 mph, you'll be an unhappy camper. (Unless you make ski porn at Valdez for a living. )

I would a agree with the 10cm+ rule if you are going from your flat tail hard-snow carver to you rockered powder ski.

The same applies when going up from a flat tail hard-snow carver to you twin-tip powder ski.

Even a flat-tail powder ski, like the Dynastar XXL should be at least 5cm longer than your carver.

one data point: My regular cambered deep snow ski is a 193 at the moment, has a turned up tail, and I'm looking for something 200+ to replace it.

My preference in the flat tail hard snow category is usually right around 170-175. So I guess I'm all for an extra 30cm.

Now that I've had a chance to ski 3 different rockers (spatulas and Moment's Donner Party and Bibby Pro), I would say the answer to this question is a resounding Yes! Because of the flat area underneath, the extra length is not a factor on 2-dimensions, but when you have powder/3-dimension snow, the extra length gives you control and makes the ride sweet. <br>
I demoed those two Moment skis at Loveland on Friday and they were a blast. The Bibby is rockered with traditional sidecut and I could put it on edge with ease. In fact, it was so easy, I thought to myself "this must be 95 underfoot", but found out afterwards it was 115. The Donner Party is a modern day (and significantly improved) Spatula design. The great part of the design is the flat area underfoot, therefore allowing you to put it on edge (granted this is not a true carving style, but rather you initiate the turn underfoot by pivoting or sliding and finishing on edge). That makes them significantly more versatile than the Spatulas and very skiable on the hardpack. Unfortunately there wasn't enough new snow to try the Donners in conditions they were meant for, but I have no doubt they kick a$$ in powder.

moment skis

a big plus for moment is the ability to demo them, and the prompt and generous response from the company makes me want to support them before i have even seen their skis

Cornice Sports in Kirkwood (the one near Bub's Sports Pub, NOT the shop in the "village") should have some PMGear 186 Lhasa Pows for demo this season.

Any chance of Green Mtn demoing Lhasa Pows this year?

It was in the September Powder magazine (2009 buyer's guide). He suggested +10 for full rocker, +5 for medium rocker, and 0 for mini rocker.
