Dynafit Low Tech Race Binding
August 29, 2009
In addition to what Jared noted, the race version lacks any release adjustment (unclear what it's equivalent DIN value is) and also lacks any fore/aft length adjustment (so be very careful with your mounting). Therefore, it's really appropriate only for racers.

Backcountry Access Tracker DTS Beacon
August 29, 2009
With the exception of the Pieps Freeride, size and weight varies comparatively little across beacons. More important (aside from functionality of course) is whether the harness designs is a good fit for your body and personal preferences. Only way to know that for sure is to try it on.

Black Diamond GlideLite Mohair Mix STS Climbing Skin
August 29, 2009
The general guideline is that compared to nylon, mohair has better glide, but less traction. My personal experience with 100% mohair skins has been that I couldn't tell the different in traction, but did notice enhanced glide in nice midwinter snow. Springtime and summer snow, no different in glide . . . but definitely wore down more quickly than nylon (which, in the case of Ascension, never seems to wear down). My expectation is that the mix will be a compromise between the two.

Dynafit TLT Vertical FT Z12 Binding
August 29, 2009
If you're very capable (and careful) with woodworking in general, and download (and read carefully) all the material from WildSnow.com, then you can mount Dynafits accurately by yourself without a mechanical jig. I think my first attempt that way took about two hours. After that, subsequent mounts took about an hour. But once I bought the mechanical Dynafit jig, mounts now take only about twenty minutes.
