Thanks for the feedback, guys!
onyx: Good catch with the abrupt edge transition... I feel like I don't have the subtle muscle control to do better at this point :( I wonder what drill I can use... hmm...
therusty: are you talking about proper crossunder skiing? Wouldn't it be awesome to be able to do that in all conditions?

At step 7 (CSIA model), our club talks a lot about lateral extension, and good angulation, but I haven't seen a lot of drills to force lateral extension. Maybe grasping the pole like a sword, then dragging the poles along the snow on both sides throughout all turns would encourage a lateral extension? (or at least dragging the pole against the snow on the outside side?) The counter-rotation you suggest -- ie keeping the shoulders and hips square to the hill... It's funny because lots of instructors tell me I ski like a robot with too much counter in the shoulders... though I can definitely feel little counter in my hips! So I bet you're onto something good with a hip counter-rotation. I bet a good drill for that would be... the hip-o-meter, where you attach the poles around your hips (like, belt style).... then ensure the hip-o-meter stays square to the hill... hmmm!
Last year I could only extend laterally on greens and fairly flat blues, but it was a blast...
docbrad: I'm torn on this suggestion. I skied in a wide stance to pass my level 1... yet every time examiners would say "ski wider" I'd see them zip down the hill in a narrow stance

the funny thing is I run across a lot of level 3 and 4 instructors who say "I have the same problem as you, I ski in a narrow stance". And yet they're the best skiers on the hill. The argument for a wide stance is you can somehow get high edge angles. based on the level 4s I see, they get on high edge angles with lots of extension in the outside leg and flexion on the inside leg. When you have one ski up a good foot above the other, I'd say that gives you all the separation you need... the counterpoint is I'm almost positive I've tripped over my own skis! during transition between edges and having the widest parts cross slightly. So I should probably get them at least a bit further apart.
SkiFox: Ah you're too kind. There are a couple of other guys who're on their third or fourth season in our ski club and they beat the pants off me. (I like the thrill of competition!) And I got over 30 days a season, with at least 30 lessons a season. Most people probably get fewer than 30 lessons in their entire life! After 90 lessons, I figure I'm actually in the dunce range. I met a teenager at Silver Star--it was his FIRST season, and he had passed his level 1, 2, and 3 instructor ski exams! He met up with our group at one point, and casually skied down a steep black doing short radius turns... on one ski! Yeah, first season. Unreal!
tdk: ohhh nonono not third time, third season!!! wouldn't it be cool if it were the third time...

could you imagine? Regarding the "fun parts", it was a berm I just wanted to go up and down for kicks. Tamest fun you can imagine! Please pardon me for the question--I only know CSIA terms... does "pre-turn" mean keeping your hips and shoulders square to the hill? (if so, in CSIA that's known as counter-rotation) What is counter-steering? Is that lateral extension?
