Tek, obviously the low hanging fruit here is setting up your boots properly. Lateral alignment alone doesn't address all of ways boot set ups can influence your performance though. Too levered forward might be an issue worth investigating. I'm sure a fitter in your area can help you with all of that. Beyond the equipment, I see a sequential edge change occurring and that may not be curable by changing your set up alone. Yes it may be a work around you developed because of the boots but it also suggests the sequential edge change might just be because you are rushing to start the new turn while hanging onto the old turn at the same time. That's working at crossed purposes and if you watch your new outside half and your old outside lower leg and you will see this pretty clearly. See all but the stance leg enter the new turn before you abduct that knee and change that edge? You have stepped off the ski so it's edge has released but the actual edge change occurs later. The good news is re-setting the timing and using tipping to release the old turn is a pretty easy fix. It still takes a lot of patience and focus to re-program the timing of your edge changes though.
Drill wise a few easy drills will encourage a cleaner release using tipping rather than stepping. Sideslips on one ski target exactly this issue. If you find yourself trying to change pressure (reduce it with an up or down unweighting move) it should tell you that you haven't tipped the ski flat enough for the edge to release naturally. It doesn't need to get completely flat to the snow, just flat enough to lose edge purchase. Remember that a side slip doesn't include any rotary though and at first resist the urge to pivot the ski in any way. Eventually allowing the tip to dive into the turn will occur but for now concentrate on the tip to release idea. BTW, the more advanced form of this one footed sideslip is to do them on the shallowest terrain you can find. So start out on a blue run and work your way to doing them on shallower terrain. That may seem counter intuitive but it's usually an epiphany for our coaches when they realize just how difficult it is to do this drill on very shallow terrain.
Another good focus drill is to notice what you do when starting from a stop, or getting off a lift. From a stop do you flatten the inside ski and allow Gravity to pull you downhill, or do you tip the outside ski onto a higher edge and push off that edge platform. When you get off a lift do you roll the inside ski onto it's little toe edge and let it draw you towards where you wish to go?
Play with these ideas and I am sure they will reveal to you just how your releases and edge changes occur at different times.
A more active drill is to do White Pass Turns but it's easy to cheat and use pressure control for the release instead of reducing the edge angle until purchase is lost. So wait on that drill until you own the tip to release move. An intermediate step would be to start doing the tip to release move from a traverse and allow the ski to dive into the new turn.
Beyond that I think replacing the pressure control release and extremely active foot to foot weight transfer with more consistent pressure and a tip to release move will open up the door to parallel shins and extending out to the side of the hill rather than upward. That in turn will allow you to use your leg steering more effectively as well. Eventually all of this leads to very swoopy feeling short turns and the trampoline like feeling Bob mentioned in another thread. From what I've seen in the Whistler training vids that is something the CSIA 4's do so much better than the 3's.
