Thanks for the input Steve. So much has changed since I was in. Always interesting to learn about those changes. What you were describing was 9 years after I left Toelz. Great training. We didn't know anything about 3-,3+ etc. Matter of fact your post is the first time I've heard them.
Although, all teams at Flint, did some training on skis, my team was the ski team (for lack of a better term), We were also the scout swimmer/small boat team (small boat, referring to the RB15). Quite a combination.
During the winter in Toelz, spent most our time on skis. Cross country in the mountains and the "flats" around Flint and downhill training. I started skiing in HS. Back then (the days of lace up boots, rope tows and t-bars) I taught myself, couldn't afford lessons. Anyway, the way I would have been taught in a ski class, would have started with the snowplow, stem christie, christie, then to parallel. This is how I taught myself. This was in WI, which means I mostly skiied ICE. Got to Toelz, started training and had to adapt to actually skiing on snow.

We'd go out for downhill training once a week or so, but we could always, on our time off go to S3, I believe it was and get free lift tickets. We used the same skiis, for cross country and downhill. Doing downhill with loaded rucks was an interesting experience. The trick was to lean FORWARD, more so for parallel. The brain is telling you... "don't go there idiot, you have 80+ lbs on your back zipping downhill, when you wipe out, you might stop when you when you hit the lodge", but it is the only way to keep the weight centered over your feet. Just took getting used to.
Steve, when you were in Toelz, were you guys still using the Chippewa boots?
