I took a ride on the Vmax boots today on a v-type, and here's what I felt in one set, on different bindings and ski. The initial impression of the bindings is that they are sleek, light and feel well-build. Mounting the bindings was way easy once I got the feel for it. Only two screws per binding! The secret is sliding the boot forward to get the toe screw in, put the back screw in loosely and then adjusting the fore/aft position and tighten. Overall the binding/ski combo was probably the lightest I've ever picked up, amazingly so.
Getting into the boots was super easy, the new lace system and rear lace holder excellent. Very comfortable out of the box. The boots snug up well without having to crank on the laces, without the sloppy feeling that you can get in a boot with a separate liner. On the initial pass the boots felt a little sharper/more responsive than my normal bindings (HO Apex), but by the 2nd or 3rd pass they felt pretty normal. No cramping at the ends was a definite bonus in maybe 60 deg water. I didn't get a chance to test the release, but with the bungee laces I would guess it to be similar to the Apex's. At the end of the ride releasing the laces and getting out of the bindings was way easier than the Apex bindings. The only change I would maybe make, other than fine tuning the binding position, would be to maybe try to blow out the little toe pocket of my back foot to accommodate a "sixth toe" from snow skiing.
As far as the ski goes, it was fresh out of the plastic, no calipers to check the fin or anything. My usual ski is an A2, and the V-type felt faster through the wakes, and easier to get under the rope coming out of the turn. The offside was fantastic, the onside will need a little adjustment to tighten it up, possibly just by adjusting the binding position slightly. The feel was easier skiing and faster than the A2, but a little more responsive than the A3 I demoed last year. Also, this is about the 8th set of the season, slightly breezy, cool air and cold water, still just working through warmup passes.
Overall, I would say both the bindings and the ski show a lot of promise and I'm looking forward to trying them out as the water warms!
