Taking a lesson from Coach Cruella is a little like drinking from a fire hose.
So I have three turns that are minimally flingy. As long as I'm under Dance Coach's thumb, he's had me doing them the Ice Dance Way: with the free foot tucked up to the skating foot heel. This is because you're skating with a partner and kicking each other or stepping on each other is a Bad Thing.
So Coach Cruella brings out the Magic Marker of Doom. I cringe as she draws out a half-circle slightly smaller than the half circle at the net end of the rink. Then she draws a line at each third of the half circle.
"Skate the circle, then go down in the knee----" Insert mad scientist laugh here, "deeper each mark. And do a three turn here." She points to the third mark.
Bear with me here. I'm a beginner skater, with historically weak three turns and fear of learning new skills that have a backward element in them. What expression do you think I had when I started this.
Was it this one?
Coach Cruella takes my hands and supports me around the circle.
Start with a T-push, down at the first mark, down at the half mark, down at the third mark..... TROIKA!
I've had some opportunity to practice these by myself a few times, and I'm getting the hang of them. I've heard of mythical 'three turns that do themselves' . And I've been told down-up-down hundreds of times. In my limited experience with this method, the three turns do turn themselves (but I have to get REALLY down in the knee) and the down-up-down motion seems natural rather than forced.
So the pros--beautiful three turns, stable with just a half hour of practice.
And the cons--I need to enter with a little more power than I'm used to. A little scary there until I get comfortable with them. These don't work for me if I have too little power.
