SG ski = Nutz??

post #1 of 6
Thread Starter 
Hi everyone.

This is a great forum, lots of useful info.

I'm considering purchasing a SG ski, I want something that will really 'cut into the ice' and stay 'stable at speed'. I ski mostly in the North East US, we get a lot of really icy slopes that I like to ski as fast as I can, conditions and traffic permitting. There really isn't very much actual steeps around, so going fast on our trails seems like it is the best way to feel exhilaration. Would buying an older SG ski just be crazy? I like to ski at 50+ mph, would they be suitable, would the sidecut make them completely one dimensional? Does anyone here ever freeski on skis like this?

Do any of you ever actually measure how fast you ski? How do you do it? Are GPS units accurate?

I take my old SGs out a couple of times a year. They do require a lot more work to make the required short turns, and are pretty much out of their element when not skiing very fast, but nothing else feels as well-planted when carving long arcs at speed. You can't make a pure arc with a radius longer than the ski's sidecut radius, but you can make those long turns at speed and in control even with something like a 13-m radius Fischer WC SC. I've had my SCs over 60 mph quite a few times.

You can go just about as fast on just about any top-of-the line ski; the speed you can reach is governed by slope and wind resistance more than anything else. Perhaps if our hills were steeper and longer it would make more of a difference. An ordinary GS racing ski would be a lot more versatile than a SG ski, and would certainly be stable enough for the speeds you would be able to reach on any hill in the East that I can think of. How big a turn do you want to make?

Opinions on GPS accuracy vary. Manufacturers and people who own them and have compared them to radar and other timing devices think they are accurate, especially when looking at track logs. People who have little or no experience with them think they are not accurate. I have a Garmin GPS MAP 76CS that I'm fairly happy with.

Modern SG ski's have the same dimensions as the old-style carvers.

My 1999 Dynastar 4X4's dimensions are about the same as today's Dynastar Speed Course Pro's.

Speed Course Pro 2007:
Length: 187cm
Front: 103cm
Waist: 67cm
Tail: 89cm

4X4 Vertical 1999
Length: 190cm
Front: 102
Waist: 68
Tail: 86

The 4X4 is pretty stiff too.

So I guess it's all relative. Modern ski's do tend to be more curvy and shorter. If you are used to the classic carvers I guess a modern SG ski won't be a problem at all. Especially if you're a big guy with some weight en strength.

My advice. Try them. Buy them if you like. I'll probebly go for the SG's too when my stuff is due to replacement.

As already mentioned, a true SG will not work terribly well at even moderate speeds. I lived in Stowe for 4 years and skied much of NE. IME the times when you could really air it out on the typical NE slopes that I have skied, are very limited. Hence, by purchasing an SG ski you would be buying a tool that might only work for a run or two on any given day and probably not at all on weekends.

There are a lot of ways to put excitement into hard snow but skiing at 50+ mph on a regular basis is probably not the best idea. (At least for the other skiers/boarders sharing the slope with you) There are a lot of racy type skis that will work better at "cutting into the ice" at the speeds that you can typically get away with than a SG.

I think that unless you're going to potentially be racing SG that SG skis are a bit overboard. Unless you're on a VERY big mountain that is NOT crowded at all you would probably be better off with a long GS-type ski (think 188ish). GS skis these days that are that long are going to have close to a 30m radius in some cases. They will not give up anything at speed. The question at that point becomes whether or not you have the skill to pilot such a tool at the speeds you're talking about skiing at. If you don't already have a GS ski (and race training) that you ski on a regular basis, I think a SG ski is barking up the wrong tree for you. What are you currently skiing on?

'07-'08 Volkl Racetiger GS's in 187 or 193 will do you just as good. Radius is very much like a SG ski. You will get more out of them as well.
