I have a pair of the 614s on my ANTs. I've put about 25 days on them, several of those days charging hard. No problems, very stable. I'm super happy with them.
I'd put them on all my skis if 4frnt could make them a bit more affordable.
Do they make them with a wide brake or do you have to bend em?
They are made by a Italian ski racing company (which I find funny due to the anti racing sentiment around here) called vist (www.vist.it).
I'm thinking of putting vist's on all my skis as they make a plate system where you can install their plates on your skis and then only need one of their bindings. On top of this you can move your bindings forward and backward on the plates, so I could fool around with what feels good, as well as putting them forward for the park and a little further back when skiing the mtn.
The plate exists this year, but it's pretty heavy. The deadbolts come with a wide brake standard, and it fits over a VCT (104 waist) right out of the box.
I completely forgot about the weight issue. So 4Frnt also has an available plate system? I know Vist has one called SpeedLock, but the bindings need special screws to attach to the plate.
I have the 4frnt 412 on my MSPs and they are working great. they can take a beating and are used by a lot of pros. you can get wide brakes for them and they are so worth it. very solid binding.
get them from the states they are a lot cheaper like 249.99US or sumthing . go to ken jones site there cheaper there.
if u need to no where to get them mountyed go to sign of the skier they are like the only place that has a guy that can mount them.(think his name is ben)
