I have exactly this setup and it works just fine. The Duke plate doesn't stiffen the ski anymore than your boot does. The Pure still feels light and lively, even with the weight of Dukes. I am three season in with this setup, and have had no issues. That said, keep a close eye on your AFDs and adjust as needed. Those with AFD troubles probably need to adjust them more carefully.

Gabe, Salomon's tech inserts failed after use in a Dynafit binding. They were recalled by Salomon, so the concern is here whether these are new inserts or the old ones. The old ones should not be on the market. As for the new ones, it's difficult to trust gear that has been through a serious recall due to complete failure.

The above answers demonstrate YMMV, but first ensure to fully waterproof the leather with Hestra's included leather balm. You need to treat the leather frequently. If you do, the glove should really never soak through from the outside. That said, in wet West Coast powder I find my gloves will become damp, mainly from sweat (due to humid and warm snow conditions). My typical day however, even on the resort, involves a lot of hiking and general touring, and I find I have to dry the gloves overnight (hang them fingers up). For these reasons I wouldn't recommend any glove without a removable liner for backcountry use, these included. If you're going on a heated hut trip you could use these, but if winter backpacking I would get a Hestra with a removable liner, as well as separate touring gloves.
