According to Voile's website (and their customer service), the flat-deck Drifter is not recommended for mounting with Telemark bindings. They are quite explicit that the flat-deck is for AT bindings only, and that the 4-hole insert version should be used for Telemark.

The product description for this item should make this clear.

That said, do Backcountry.com plan to stock the 4-hole insert version?

In response to Jack Wizo: On the contrary -- inserts are much stronger (in terms of pull-out strength) than "wide-thread" screws. The difference is huge. The factory-installed inserts have a wide plate on the underside of the ski. See here for photos: http://www.skibuilders.com/howto/skicon/inserts.shtml Bindings mounted to K2 inserts may be coming loose because the machine screws are the wrong length (a big problem with Switchbacks, for example, which need a longer screw) or wrong size; because threadlock is not applied; when screws are overtightened (stripping thread of insert) etc. I'm not necessarily arguing in favor of inserts. They have their own disadvantages. But under optimum circumstances, they're substantially stronger.

You can put your telemark bindings on the flat deck version. If I were to choose between the inserts and the flat deck, I would choose the flat deck. I do not alpine ski. I use Hammerheads, which use a 6 hole mounting pattern that the inserts do not accommodate. There is a insert adapter for the HH, but I don't want to pay $60 for it. It's not that telemark bindings can't be mounted on the flat deck, it's that AT bindings can't be mounted on the insert decks. My personal feeling about inserts, is that they can come loose, causing the screws to not be removed and/or tightened, and inserts don't have the pullout strength that you'd get mounting wide-thread screws into the ski. K2 tele skis with inserts are notorious for these issues. But despite those words, I have had bindings rip out of wood core skis that don't have metal in them, as well. It was off of a big drop going fast, but that just proves that no mounting is 100% guaranteed to never come out. Telemark bindings tend to have a lot more torque put on the back two screws, so that is always something to bear in mind. Can't tell you what BC.com will have, so maybe Alexander K. can give you an answer for that. Hope that provides some level of insight and help. Happy turns.
