Does 2.5 inches really make a difference?

post #1 of 11
Thread Starter 

I know - demo both and see what you like and I will but curious on opinions.  I am looking at Line Prophet/Influence 115 and thought hands down would go 179.  Now I am asking myself how much diff does 2.5 inches make and just go with the 172 for agility.  I do not care about ^&%&^ swinging who is on the longest ski - I care about what is most fun to me and functional.  I am an east coast skier and tend to prefer SL race skis as my everyday ski since they have excellent grip and quickness.  This ski is replacing a 180 heli daddy (126-99-116) that I thought was a good ski - great in powder not so great elsewhere.  I am 5'10 260 and consider myself to be a good skier - can ski pretty much anything at any Western resort in any condition but do not ski at ultra fast speeds- I ski fast but not uber fast.  So the question - does 2.5 inches really make that much difference?

I'm 6'2" 180, and have a 2010 Line Prophet 100 179. In deeper powder I thought sometimes the 186 would have been better, but then I had to own up that I just need to learn to ski powder better. Having said that I will add that for me on anything but more than 12" of powder or really icy/firm conditions the Prophets felt unbelievably good - great float but very snappy turners! The only problem I had was the cap under the binding got banged on some rocks and started fraying - had to repair that with marine epoxy. The Influence has that hybrid cap/sidewall construction, so it might be a little more robust in that regard.

 

Seriously, at your weight I wouldn't think you'd want to go any shorter than the 179. My 179 Prophets have an actual running length of 149cm. They're twin tips, but no rocker, and the Influence has some, so it will likely ski even shorter.

 

FWIW  I don't think a couple inches makes that much of a difference overall, but I do think 172 is probably too short for you. I suspect a lot of folks here will tell you to go with the 186 due to your weight.

I would agree that 186 would be a better length. T 186 P115 will still be more maneuverable than the 180 heli daddy it is replacing.

Yes it does, but if you're going to be making short turns most of the time and aren't going to be making high speed gs turns, I'd say go with the 179‘s because you aren't going to benefit from the additional high speed stability of the longer length and therefore would be sacrificing some agility (albeit not much) for no reason.

172=Way Too Short.

Unless you're primarily billy goating or hopping around really tight trees I'd go bigger for sure.

In my experience, a difference in ski size significantly impacts the feel of the ski.  I'd demo both, seriously.  I have found I can't extrapolate the performance of a different sized ski from demoing a different size.  I've hated the thing in one size, loved it in the next.  Found the ski changed from being unstable in a shorter length but highly maneuverable to being not nimble at all but stable at speed in a longer length.  I didn't use to find this back when we had straight skis, but because in most cases the turn radius changes in different lengths, that the ski is quite different from one length to another now that we have shaped skis.

No kidding. My reaction too. But I digress.

 

Yes, (will keep a straight face as I answer) length matters. Mainly (remember, class, we're talking about ski tips here, so stop that snickering) because of the relation between torque and distance. Try holding a book overhead, then hold the same book out at arm's length. Notice how it feels heavier at arms length? Distance from the rotation axis has increased, given constant mass. So more torque. Thus an extra 2.5 inches will require more effort to pressure the tip during a carve. (Well, ski is also heavier, and has more mass further out, but that's other stuff.) The length issues will mainly be about your height, skiing style, and leg strength. Choose a seriously stiff ski (determined by cross sectional area, mainly) for your weight, then figure that something in the 180's if rockered is fine. 172 is too short. Period. 

 

Now please go revise your title.

Just realised I misread the question - I thought the OP was debating between 179 and a longer length, not between 172 and 179. 172, additional agility notwithstanding, would be too short.
