Now is there an RF binding that has the race toe (Not that I need a hight din, I just don't like the idea of retention instead of upward release)?
The Tyrolia race toe piece releases laterally only. They avoid an upward release feature to accommodate a lot of extreme backward positions many racers find themselves in from time to time when they still hope to avoid a binding release.
I've never used a Tyrolia plate so I'll defer to others on this. My Free Flex bindings are drilled into existing ski plates that came with the skis.
Tyrolia/Fischer Rail Flex bindings have both a vertical and horizontal release feature. The Rail Flex system does not have a race toe piece. Maximum DIN is 14 on this year's Tyrolia version (Max. DIN is 12 on Fischer's version of Rail Flex).
The Rail Flex Plate must be drilled to the ski. The binding is then adjusted to the boot length using a scale on the underside of a mechanism that connects the toe and heel pieces. The assembly then slides onto the rails of the Rail Flex plate and is screwed down with a single screw.
The same screw can be adjusted to move the binding assembly 1.5 cm forward or backward from center. To re-set for another boot size, unscrew the screw, slide the assembly off and reset using the scale mentioned above and slide the assembly back on the plate's rails.
Hope that helps some.
