What a great thread!
My wife and I (with a couple of her gal-friends) just returned from Revelstoke for a few days. What a beautiful place! Can't wait to go back. I now have a better understanding of what kind of snow you all talk about when you come back!
If I may offer a few observations and suggestions...
In many physical activities, simple strength can be used to overcome less-than-perfect-technique. This can often work against the ladies who may be trying to learn from a guy. (We guys usually have stronger muscles) My wife is very tall - 6'! (good from a leverage point of view), and very slender. (See: August 2010 ladies ride - glamor pic) That height is nice when it comes to stepping over the seat when transferring weight, and nice for leverage, but her lack of 'mass' and strength, means she actually has to be better at technique that I do, because I may have enough mass & strength to overcome a technical error.
So, in a way, this is directed at the guys: be patient and remember that they actually have to be 'better' than us to be able to do the same things we do.
This last trip showed me something: Just how important it is go get out there more frequently. Three days straight of her riding, (and much nicer snow) she got a lot better! My body is broken right now, so I spent a looong drive, and 3 days watching. And it was worth it. So, I'll add my agreement to the concept that going the next day after a great day (learning progress) is invaluable. Just find a way to do it if you can.
On the sidehilling concept:
I suggested she find a bowl, one with a gradual slope. And, start low, and start on your 'strong' side. Make one low pass, as long as you can go, if you need to turn out, fine, the bowl makes it easy to return to the vantage point. Then, make another pass, same direction, slightly higher (and steeper), again, as long as you can. After you have 10 good passes on your strong side, your body has started to learn how it 'feels'. Now, you can start on your 'weak' side, and again, start low, and work your way up, just like you did on your strong side.
Some have mentioned that there is a commitment needed, when you select your path. I couldn't agree more. Also, have a plan on how to bail on your line if that happens. And I mean specifically, not just 'I'm going to turn out', but how are you going to shift your weight, turn the bars (or not), what you're going to do with the throttle and brake, etc. If you take the time to understand what each of those actions does to your sled, your momentum and how that effects your path of travel, you are in a much better position to 1) continue your chosen path, 2) recover if you have to adjust or 3) bail all-together, but not crash or 'stuckit'.
And, don't be afraid to log some time in the gym. Muscle and strength endurance is a huge benefit to this fantastic addiction. And, you can be strong without sacrificing any femininity!
I am so proud of my wife for her efforts and progress during this last trip! It was very rewarding to see her have fun, and work through some of her fears and apprehensions. I am a blessed man.
