There´s some info on their website www.vist.it
(English version available) but the site has never been very good IMO.
Vist skis have been around for about 3 years. They are meanufactured in a small factory in Italy by Horst Gamper, the man whose name bears each Vist WC plate ("made by Gampy" - not Forest Gump...). They are all traditional sandwiches with 2*titanal, slightly less demanding than real worldcup skis are because those guys and gals are not his target group (neither himself nor the four companies he´s manufacturing skis for, e.g. Nava, Duell, Vist, will be able to pay the money to become part of the official Pool).
I owned a pair of SL prototypes 157 cm three years ago, still before FIS changed the length limit. A nice ski, tuned to .5/87, fast, snappy, stable enough, very good grip (never used them in gates).
A friend of mine owned a GS prototype of the same time, 183 cm/21 m, and was highly satisfied after some good results in regular races against guys 20 years younger. I skied them as well and found them nice though somewhat less aggressive than some racestock skis of other brands.
Vist considered the introduction of its skis back then but then they somehow concentrated od the bindings and Speedlock. I took part in a Vist demo last October in Italy and they told me that they considered the skis mostly as carriers of Speedlocks. The skis they have (a GS, a SL, detuned Gs and SL and some allround model) had the topsheet reading "Speedlock" (my old Vists were regularly Vists).
I have the lengths, dimensions, radii somewhere but no chance now to look it up.
There´s some info on Vist GS and SL on the Japanese site refered to by sywsyw and me in the last posts of the Boot lifters thread.
Should be these two:http://www.kandahar.co.jp/catalog/pdf/04_05.pdfhttp://www.kandahar.co.jp/catalog/pdf/06_07.pdf
I also have a pair of VIST 614 binding and have no problems. Last winter I changed the standard binding screws for the Speedlock pins and have been using the Speedlock Pro system (essentially the VIST WC Air plate + the binding). It works nice but doesn´t give the 55 mm heigth and there´s no chance to get higher.
Last year they improved the design adding some sort of security pin to prevent the levers of the plate to open unintentionally. The system is not so easy to adjust as regular demo bindings, some (frozen) snow in the holes might be a problem.
The interchangeability of pins and regular screws makes it possible to use the bindings both with the Speedlock plate and normally with screws. You break/destroy/bend/damage the skis but you still have fully functional binding, not like some other fully integrated systems.
