I thought I would throw this up. I spent a week skiing with Harald at my home mountain earlier in March. I told him that my goal for the week was that I wanted my SRT's to be as perfect, seamless and effortless as his are (knowing in advance that I will never achieve that but maybe I could get close). And that's what we did. We worked non stop for a week on brushed SRT's and worked a lot of super short radius turns. I did get to the point to where maybe 85% of my arcs had two thin lines from the apex to release, which is what a perfect brushed carved arc looks like. The other thing that gives guidance as to how well one is doing with these is that when done properly the skis will pull one through the arc as they aren't brushed in the bottom half of the arc and the tipping and extreme CA make the skis track. All great stuff but my main point is what happened after Harald left.
We finally got some fresh snow on top of the ice that had been created by the very warm spring conditions. Its a very low snow year at my mountain (running 40% of normal snow fall, ugh), so we have a pretty bumped up mountain even after a good bit of melting. We got 3" or so of fresh snow on top of the ice and I went out and skied our ridge under some challenging conditions (a little better than dust on crust, but hitting sold ice on every arc). I was blown away at how great and tight my turns were. I was cutting my tightest off piste slalom turns ever, and skiing the challenging conditions was actually easy.
Most skiers on this forum work hard on their skiing because they want to ski well and have fun off piste (I realize that may not be everyone but it's most). I know its also been said before that skiing well off piste is all about the BPSRT (bullet proof short radius turn). But it is so true. And the better your BPSRT'S are on piste, the more it directly translates to them being good or great off piste.
Yes, a broken record on this forum, but I was blown away by how quickly that work translated. And remember, if you can't do them on piste, for sure you won't be able to do them off piste. As Harald reminds me all the time, go for perfection on piste because some things (essentials) always deteriorate off piste and in 3D snow.
