Hey,
am rethinking my fibrework as my skis turn out quite stiff. My Idea is to use biax Carbon for torsional stiffness and uni glass for a more relaxed flex - thats the way I like it, I want the ski to have edge grip when I want to.
However, the downside is that the ski is less forgiving in crud and other uneven terrain...
So I just want to ask around how you like your skis: Hard flex, soft torsional flex, the other way around, mid/mid, and so on. What are your thoughts regarding the balance of torsional stiffness and flex?
Cheers

Torsional stiffness vs. Flex stiffness - how do you like it?

Here is my non-expert opinion.
I think that tortional stiffness is always good, so the more of that the better, particularly for on piste. It is probably not so important in soft snow .
The same goes for overall stiffness. On piste a stiffer ski will be better for powering through a turn with even pressure over the entire length of the ski, but in soft snow of course this is a huge disadvantage. In short, Tortional stiffnes is good, Fley depends on what you want to do.
I'll be interested to see what others say here.

I am nobody. Nobody's perfect, so I must be perfect.
After using 750 triax Glass for the last 5 Pairs I am now thinking about trying 300g Carbon biax and 400g Glass uni.
On one hand I want to save weight with the Carbon and get a torsionaly more ridgid ski. On the other I want to keep the "glassy" flex of my former layup. What do you think? Does it make sense?
The junkysupply simulator says the carbon/glass layup will be e few gramms lighter while being slightly stiffer than the pure glass layup.
Another thing that came into my mind:
To receive a certain stiffness of a ski I can
a)use a thicker core with less fibre or
b) use a thinner core with more fibre.
In case a) each fibre needs to take more stress than in case b) and vice versa. So will a ski with thinner core and more fibre keep the flexpattern for a longer time? Less stress for each fibre -- less fatigue?
I hope I didn´t mess up the technical vocabulary to much, but I am not an engineer:-)

Funny, want to do the same, but less glass, only 220g Uni glass. If you need 300g Biax Carbon write me, I got a lot of it. And it makes a lot of torsional stiffness :)Hannes wrote:After using 750 triax Glass for the last 5 Pairs I am now thinking about trying 300g Carbon biax and 400g Glass uni.
