Alternatives to Dynafit bindings

Last night in class Joe said he got to get a hands on look at the King Pins and was really impressed. His wife has them mounted on her skis so there should be some quick local feedback for you.

Dynafit Speed Superlight.   Heel doesn't rotate.  I busted my Dynafit Radical STs heelpiece after 10 days.  My SSL have 50 days on them with no issues.

Only negative I've found on the SSL is the length isn't adjustable, so works with just one pair of boots and you have to be very precise when mounting the heelpiece.

The length is adjustable if you get the plates:

... toe, heel, or even both.
Also, the elusive Dynafit Speed C-One:
www.snowinn.com/ski-store/dynafit-speed-...e-c-one-red/612547/p
... combines the Speed Radical toe with an SSL heel on an integrated 25mm adjustment track -- Skimo Co might know where you can get a pair.

Turns out my binding did not break this time, it merely disassembled itself. We were lucky tracking Eric from Marmot down who fixed my binding in no time.

Did the heel disassemble? I've been told to periodically tighten (but not overtighten, because they will strip) the top screws that hold the heel together from time to time. I have noticed they loosen up after ~10 days of skiing. So far I have no failures on my Speed Radicals (~40 days of mostly spring/volcano tours) and Radical FT's (~30 days of mostly powder touring). The only issue has been unwanted heel rotation when using the risers on the speeds, but that was fixed with the anti-rotation add-on that recently came out.

I know some folks like to go with a radical toe and old-style vertical heel.

^ Some people go with the Plum Guide heels and the Radical Toes. I think this offers the best of both worlds personally.

I just picked up a set of g3 Ions... they look promising

FWIW: ICMF rules require the toepiece and heelpiece to be from the same manufacturer. The rational has something to do with liability. If you don't enter any skimo races probably not BFD, unless you want reliable release settings.

I bought a pair of G3 Onyx (red) binding last year. I like them. Skied both resort and backcountry with them. Only released twice, both times were needed. I bought extra mounting plates so I can swap from winter to spring skis, takes about 15 min.
