In a way the telemark turn is in parts a waist steered turn (edging the inside ski and driving the outside ski forward), and the waist steered alpine technique is partially a telemark turn (uses the inside ski and drives the outside ski forward around the inside), so it seems like some finer points of the alpine technique might also be cross applicable to hone a telemark carve. I don't have much in the way of the kinda consistent pitch groomers to work with that one would need to really put good practice/experiment time in, but I'm playing with it when and where I can. At any rate, being one to always be hunting, besides the alpiner vids I also stumbled into the telemark site shared below. It is a pretty interesting site, covering a lot of telemark technique aspects. And although the telemark link doesn't go into the finer points of waist steering per se, nor does it have videos, it does in fact show that there are efforts to apply aspects of the alpine racing world's waist steer carve to the modern telemark carve. Possibly the most obvious clue is that the website tutorial promotes the idea of performing the edge exchange before the lead exchange, followed by a slow lead change after the turn has been initiated. I can attest that this is not easily done when one has spent years turning telemark skis traditionally, whereby the lead exchange and edge exchange happen simutaniously. Regardless, other's might also find the below attachments useful, interesting and/or informative.
