I bought the skis, for 80 USD in the end, they are stiffer than i expected, and i could compare the stiffness with a brand new pair of dynastar GS 195, i would say they were 90% the stiffness of the Dynastar, and they weigh 8.5 kg, the dynastar is heavier but i think because of the Look bindings...using a ruler i found the measurements are similar, the dynastar has the tip a bit narrower.
I use the Volkls at the minimum DIN, 11, and they snapped every time i crashed
i will leave the fischer bindings at 8 for start, not knowing the ski yet, it's interesting that their heel also rotates sideways.
In my country i can't find a cheap 35m GS ski, because there are few racers and the only good deals i got were 2 pairs of 23m radius Volkl Racetiger and Rossignol Radical, used by Edit Miklos, a WC athlete, some years ago ( 150 usd for the Volkls with Comp 20 bindings and 70 usd for the rossi with plate only, no bindings ), and i don't think i will find a 20ish radius anymore because they are not legal since 2012.
So basically i chose them because of the limited market offer in my area, and i am very happy with the way the volkl skis, i took care of them this season, and got enough skill to repair the bases after some rocks and to sharpen and wax them properly, so if i take care they should last some time more, even if the edges and bases are thin.
All in all these 80 usd were spent just out of curiosity for a larger radius ski, reading all you said i am aware it is not the same thing as a true GS, but neither am i a true athlete...i just have the motivation to improve my skills and i really feel i have improved this season.
If sometimes in the future i will find a true GS ski for a cheap price, i'll go for it, but for now there aren't even any for sale around here.
i have a friend who is a young racer and in the next 2 years he wants to change his nordica GS and he said he will sell it to me for a good price if the sponsor will let him keep the ski
thanks for all the explanations, with this forum i am learning something new every time i read a new topic :)
