Oh jeez. Nothing like that!!!! But its funny to hear.

Yes, some modern wide skis hold an edge on hard snow very well, but any skier will ski better on hard snow with a narrow under-foot ski than with an equally good wide ski. One of the local PSIA division staff clinic leaders was commenting recently on how a certification candidate on wide skis will have a much harder time meeting the standards than if they were on skis 66~73mm underfoot...yes, the excellent skier will do well, but the less than excellent skier won't do as well.
Thanks for giving some great advice! The whole thought was to have to try harder. Where some might think this is a bad idea, you said my thought as the cons. =) I want to work harder, that is the idea. I don't mind a tougher learning curve. I use my legs a lot for my job, the more muscles I can build in my legs during winter activities, the easier that first week of work is.

Cons: the skis are super stiff. And the magne-traction can be a bit tricky to get dialed. As one TGR reviewer noted, "hold onto your ass!"
Still, you get all the steeze of a big, long, fat ski with crazy graphics, yet you won't skid out on your Michigan hardpack. What's not to love?
Great idea, except I'm going for a brand line up. I don't know how I'd like stiff ski's though, I like that smooth Buick Lesaber style ride. Smooth and floaty. haha. I will check them out. I will still check them out, and keep them in mind to demo if I ever get the chance. The more I can learn, the better.

I've been getting increasingly curious about this...
I can do the math if somebody has the formula. But I cannot think of a good formula to represent the difference.
If you guys give me enough info on exactly what you want, I might be able to come up with some sort of figure.
Okay, I've stewed on this a minute. There is a LOT of factors to take into effect.
But what I think we need to figure out is force applied to get it on edge. Say 45.
But we'd have to have some sorta defined number for the lenght that would be from the ski to the knee.
I was thinking about that part, a longer legged skier would have less trouble with wider ski's due to more leverage being available to apply to the ski from the knee/legs then a shorter skier. Theoretically, without the math, this would make running lets say a 100mm fat ski easier for me to get on edge at 6'3 and a 36" inseam then lets say somebody who is 5'8 (an average height) with a 28-30 inch inseam.
Stupid physics class. Grrrr. Just more leverage to apply.
But the other question is.
Do you measure from the bottom of the boot, or from the ski? What effects would a lift plate give?
use a basic generalized number, we'll use 45 for our ski angle to the slope.
Got all sorts of numbers here, but I don't know how to figure out what the "force" number is we are trying to get or where to get it.
I'll yack with the math teacher there. He will know.
Its just trig with a bit of physics.
