Hey, so the DIN toe is the main advantage of the RT over the Dynafit TLT Vertical bindings?

AWA, you should look into the PLUM guide binding. It has longer pins than the RT and stronger toe springs. It costs the same and if you are prereleasing from the dynafits, the RT would be worse since the pins are even shorter.

Just to be clear, the adjustable toe release only works if you have the toes locked. In ski mode, they release exactly the same as dynafit or other tech bindings. So unless you are skiing with the toes locked down, the adjustable release applies for the uphill. Skiing with the toes locked is still not recommended.

Also, the fact that they are all metal. cam seems to say that his dynafits caused him a tib/fib spiral fx... i'm curious if he was skiing in locked mode, and how much he weighs? I always ski locked out because I tend to fly out of dynafits if not locked out because I weigh ~200lbs. Even when locked out, I've never had a problem with them releasing in a crash, and I've never had an injury due to nonrelease. Actually, all of my bad accidents can be partly or wholly attributed to prerelease of a heel or locked toe, most of the time because of all the chintzy plastic that dynafit uses. Can't wait until I have some $$$ to pick these up, but I am interested to see what people say about skiing with these locked out... it seems that it would be a stronger lock, and may actually cause some injuries if you weren't careful.

The toe release could potetailly be safer. I got a spiral tib-fib fracture in my Dynafits due to the mechanism of release (although it was my own fault the bindings were not adjusted correctly). The Dynafit will release at the heel first, then the toe will relase next, in sequence. This sequencial release creates a large twisting force = spiral tibia fracture for me. I can't help but wonder if the toe had released SIMULTANEOUSLY that this might not have happened. No proof without playing with a pair, but I could see the potential benefit. I still love Dynafits.

There is no need for a din in the toe on a tech binding because of the way the bindings are meant to release under twisting motions. So even if there was one it wouldn't be advantageous.

Sorry my mistake..an adjustable toe and heel but not exactly DIN.
