Hey MWSucks. First of all, don't just try to rush into it and go right to that "uphill edge". I assume you are talking about the outside edge of the inside ski. It will take some patience, solid balancing skills, some athleticism, and a pinch of silly experimenting!
1) Random Thoughts- you'll need to get a feel for what movements it takes to get the ski to do what you want it to. I heard a quote once "The outside ski is where the action is, but the inside ski is where the activity is." what I'm saying is that if you turn your outside leg inward, your inside leg has to turn OUTWARD the same amount... in fact I look at my inside leg as my trigger nowadays, that is to say I turn/tip it outward first and match the outside ski to it! (Geez, these really are random thoughts) Enough. 1)Stand on one foot (no skis on) and tip it outward without tipping your shoulders. It's tougher than you think. If you can accomplish this without losing balance, you'll see that the center of your pelvis will be directly over your foot...that's a good start.
2) Rail Road track turns - on green (fairly flat) terrain, let your skis glide down hill. Stand exactly 50/50 on both skis and once you have some momentum going, tip the skis (not your upper body) onto their edges and be patient. Strive for the 50/50 feel as the sidecut of the ski guides you into a turn and across the hill. Don't overthink. Don't try to do anything but tip the skis AT THE SAME TIME, THE SAME AMOUNT. If you don't allow the skis to skid, You then might start getting a feel for the skis working together and develop an awareness of the inside leg and how it feels as you turn.
3) Royal Christies - Easy terrain again. Start making some turns with the inside leg awareness you developed from the RR turns. Get a feel for it. Then, as you begin to execute a turn, slowly lift your OUTSIDE ski off the snow about an inch and let your INSIDE SKI (Uphill edge) stay activated and take you around the corner. If you lose your balance, the other ski is there to catch you if you need. Remember where your body was when you stood on one foot with no skis on?
My humble opinion on weight distribution is to stand on your feet the way you would any other time in your life. If that gets confusing, just shoot for 50/50 and let the forces you build PUT you where they want you. If you try to contrive a 60/40 stance you could get caught in the trap where you are striving for a POSITION and not a fluid movement. Truth is, at different points in the turn, you might start 50/50, gradually make your way to 80/20, and back to 50/50. Some turns are more successful than others... I won't pretend to know what that means to you!
Oh, and yes, a good feel for inside leg activity WILL make you a tougher contender out there.
Sorry for the Jibba-Jabba (where's Mr. T?) Hope it helps.
