K2 Pon2oon w/ dynafit bindings & quiver killers?

I am looking for comments from those with experience skiing dynafit bindings on big waisted skis like a Pon2oon. Basically, are my boots (Scarpa Matrix) and the binding enough to drive the ski?

I only own AT boots so I have the choice of putting on a heavier binding (e.g. Duke or Baron) or dynafits. I am considering using quiver killers on my current AT skis and the Pon2oons then I could swap my existing dynafits between skis.

I am 150lbs, I don't huck or generally break gear and rarely have my dynafits release on me. My boots are three buckle Scarpa Matrix. I got the Pon2oons mostly for in-bounds powder days at Alpental with some side country use as well. My other skis are Dynafit FT10.

Thanks

The bindings are plenty strong. IMO the boots are way too soft to drive a ski that big in mixed conditions. Everyone has their own stiffness preferences, but you won't notice the difference of a burlier binding with boots that soft.

Also, use Binding Freedom inserts. Jon designed both versions and the BF version is superior and cheaper.

Short answer.
Dynafits on 132mm waisted ski=  hell yes...no hucking > 10 ft though!
Scarpa Matrix on 132mm waisted skis= Hell no...unless its UTard blower which it ain't gonna  be in the PNW.

I used Dynafits + Quiver Killers/binding freedom inserts the last two seasons on a couple pairs of skiis,  Karhu Storms, which have 100mm waists and Voile Drifters which have 128mm waists.  

When I was touring I used Garmont Megaride boots -- four buckles, but somewhat soft.   This year when a lift was hauling my fat ass up the hill I used a pair Garmont Axions -- which are much stiffer (and heavier) than the MegaRides.

Moving bindings between skis takes about 20 minutes -- It might go faster if I used my battery powered drill on the screws -- but I've damaged much thicker snowboard inserts that way -- so I do it with an ordinary screw driver.

Under soft snow conditions I found the MegaRides sufficient for the Drifters.  For example, last season I skied at White Pass on a day with 22 inches new and the combo worked great off the groomed runs and tolerable on the corduroy getting back to the lift station, though with a bit of a "lunch tray feeling".  While touring on the Drifters -- I never felt like the MegaRides were not enough boot for the Drifter.   On the 100mm waisted Karhu Storms the MegaRides were fine in all conditions at speeds below 35 mph.

I'm 6ft tall and weigh ~240lbs -- In bounds I sometimes ski somewhat fast maybe ~50-60 mph max in uncrowded conditions on smooth groomers.  I also occationally fart around in the terrain park, but I stick to jumps and the half-pipe and avoid rails and boxes as steel hurts a hell of a lot more than snow when you fall on it.

Overall I'd say:

Dynafits are plenty sturdy and ski quite well -- IMHO for a touring setup heavier AT bindings don't make sense if you have boots with Tech Fittings.

If you are planning on spending a good chunk of time in the park and/or zippering moguls -- just get an alpine setup -- Alpine bindings are cheaper and have more release angles, besides you'll want a sturdier ski with thicker edges for that kind of stuff anyway.

Binding Freedom inserts are a little easier to install than QuiverKillers.

I asked similar questions about 2 years ago, lots of people chimed in with good info to help: www.turns-all-year.com/skiing_snowboardi...68.msg73325#msg73325

Since then I've ridden my ft12s on both 182 BD zealots (110 waist) and 186 Lhasa Pows (112 waist) with dynaduke plates. In fact I got so lazy this year on swapping for inbounds and BC setups, that I rode the Lhasa/ft12 combo in bounds a ton this year. Things are burly, never pre-released, and I released ~3 times when I certainly should have.

Only thing I have started to notice is a bit of vertical "play"/slop/jiggling/what ever you call it in the toe piece. I'm unsure whether it is me exerting enough vertical force downward to ever so slightly open the toe pincers for a split second, or whether the tech inserts on my boots (BD methods) have started to wear out after a couple seasons and develop some slop in the interface.

Anywho, the binders are burly, but I'd tend to agree that your boots will likely be the weak link.

Also, forget quiver killer. Jon from bindingfreedom is the true inventor.

^^^ you might want to have that setup checked out. Sounds like you're developing enough slop to cause you some potentially big trouble. Check that the sole isn't hitting the toe wings and opening them and also check that your binding screws are all tight.
