"Telemark" skis mounted with Randonee bindings - a faux pas?

My impression was that AT binders on tele skis was OK, but the reverse might not work, since the forces generated by telebindings could rip out of a non-reinforced ski.

Maybe that is possible with the newer high tension binders, but for the most part that has not been an issue in my experience with alpine specific skis.

I agree with Marcus and Randy that they can be mounted AT on tele.
The real trick besides preset tele screw holes is to determine boot center on the ski to get a good location for the bindings.
Not going by telemark specific toe piece locations. AT bindings are different in that regard.
Good Luck,
Joe

My wife and I have been ski AT with tele bindings forever, including Tua Excalibur, Excalibur Plus, Excalibur Mito, and Mito; Black Diamond Vertige, Kneissel Tourstar Ultra, Atomic Tourcarv Alpin, Volkl Snowwolf, and a pure alpine ski, Atomic R:EX with no problems (every kind of tele binding). I did mount tele bindings with Voile release plates on some older Volkl alpine skis reputed to be great tele skis and, I think with foam cores, and I tore the bindings out a couple of times.
