Within two years of using my first Dynafit binding, I had sold off or given away all other bindings and switched over to Dynafits exclusively. Not only that, but so has my wife and our ski locker looks like a Dynafit show room! About half of our Dynafits are Comforts as they have a good range of adjustment and are intended to be used with brakes. I like brakes for everyday skiing, but tend to go with removeable leashes (and thus the TLT Classic binding) for expeditions.

I had to go AT from Tele because of a bad knee. I wanted a light binding, that I could use mainly backcountry and occasionally in resort. These bindings are worth every dime, they are light, easy to use. The three heel heights for skinning make climbing easier because the transitions of rotating the heel is smooth. I always had trouble with climbing bars and find this set up much easier.
They are daunting at first because they are so different, but 1 ski and you'll be a convert. Like the guy above mentioned the only down side is having to clean the holes in your boots so the toe pins will go in. A Q-tip does the trick nicely.
I come from a tele set up, so I cannot comment on how this compares to a traditional alpine binding, but I can say it it was easier to tour on these dynafits than any tele binding I have had. I opted to mount them with the brakes, which have been great for in resort. When you backcountry and go to turn the heel for touring, make sure you press the brake plate down first
(took me a second to realize this)
I mounted them on Black Diamond Joules and have been very happy.

Being so different from all the other bindings, I was concerned about the release mechanism, especially after having had ACL reconstruction. I was also concerned about stiffness, especially torsion stiffness of the binding, since there are no plates that connect the front to the back part.

The obvious advantages of Dynafit versus the more classics styles are:
* Much lighter weight.
* For climbing, the attachment mechanism with the two pins in the front minimzes friction.
* You do not have to lift part of the binding for climbing.

These advantages where the primary driving factor for me trying Dynafits. My previous binding was a Fritschi Diamar Freeride+. No doubt a fantastic binding.
The release mechanism of the Dynafits looks to the user very different from that of a traditional binding. The front piece has a ski and a climbing mode, but no DIN adjustment at all. In climbing mode you lift up the little lever which prevents the front piece from opening for all practical purposes. If you do not lock the binding in the front when climbing it will come off easily. The downside of this binding is that if you get in an avalanche during climbing, your skis will probably not release.

The back mechanism has two DIN adjustments. One adjustment controls the release around the leg-axis and the other adjustment controls the binding release around the axis that is perpendicular to the ski in the ski's plane, e.g. if you fall forward.
I only have one major crash on the binding so far in which the binding released without any problems. Based on that crash, comments from my primary touring partner, I have gotten a lot more confident in the bindings release mechanism. Keep in mind though that my experience with the binding is not statistically significant.

Torsion stiffness of the binding seems better than on my Fritschi Diamar Freeride+. One theory is that the boot has no play in these bindings compared with traditional bindings and therefore prevents any torsion flex that would have been provided by the loose traditional binding to boot connection. You are also much closer to the ski with these bindings. That certainly reduces the leverage on the binding and may reduce torsion flex, too. Overall, I was very positively surprised. I also swapped the ski from a K2 Shuksan to an Atomic Kailas when I bought the Dynafit. It could be that some of the improvement comes from the ski change.

There are a few disadvantages: The front holes on the boot can easily collect snow or ice. This can make it very hard for the binding to clip in properly. It is also much harder to adjust the climbing angle on the binding with your poles. The leashes that come with the binding are not great.

Any tips from more experienced Dynafit users much appreciated.

So far, I am in love with these bindings.

If you want minimal weight, but a dependable binding, this is a great choice.

These bindings are great. Light. Strong. Durable.
People worry about how aggressively they can ski in them. Mark Newcomb has skied crazier things in them (Bubble Fun Couloir, Black Ice Couloir, Otter Body) than I ever will so I'd say they're fine. They're super light and I've never had a problem.

Very light, extremely dependable, and simply the best binding for touring out there. If you are looking for something that will hold up and allow you to go on all day tours without weighing you down, this is the binding for you.

Stiff, durable, light, dependable, tours better than anything else, simple elegant engineering
