how to pick up bad v1 technique

Last week I pasted a quote from johnnyklister about why we should mostly ski alone, as this allows us to focus on technique. This came up again when skiing classic Saturday - my group stopped to talk about how to not "slap" the recovery ski and then we stopped again to talk about how hard it is to do it right even when focusing on the technique. The problem is we've spent years perfecting bad technique and this is now programmed into our neuromuscular memory. It will take lots of dedication and focus to de-program this and re-program the right technique. Here is another version of this from Master Skier related to V1 (and its related to why we didn't want to practice V1 on the softball field)

  This is all well and good, but I don't think it addresses the real issue. The problem lies in the fact that most people V1 on terrain that is not appropriate for V1 and, in their quest for more glide, develop the "shoulder drop ". 
  How many of us have been in this situation before? You are out on a long ski and, after three hours, you are getting tired and need that big burrito at the lodge? 
  You crest that last steep climb in V1 and the trail mellows out to a nice false flat. Instead of downshifting into a nice easy, quick V2, we just keep grinding away at V1. 
  "What is wrong with that? " you ask. Well, nothing really. If you keep your V1 really slow and concentrate on correct hand position, driving with the abs in smooth, short strokes and moving well from ski to ski! 
  Here in lies the problem. Most skiers do not do this. As the terrain mellows, skiers are not content to continue on the slow, methodical pace that correct V1 sets. We start looking for more glide. 
  Now, instead of shifting into V2 like we should to get that glide, we start to adapt V1 to try and keep up with the quicker ski speed. Because the V1 is a short motion meant for very steep terrain, it starts to get weird when we take it out of that environment and transplant it into another.
  In order to lengthen the stride and build more momentum, skiers will subconsciously start looking for more ways to get glide. The only way to do that in V1 is to stretch out the compression phase of the stride. And, the only way to stretch the compression phase is to drop the shoulder! 
  Whammo! All of a sudden, instead of compressing straight back with the abdominals and driving forward, we are now compressing to the side and down. This engages muscles that will fatigue early and causes all sorts of problems for your back and shoulders over time. 
  Not only are we looking at quicker fatigue times (ironic, since we stayed in V1 to conserve energy in the first place), but practice makes permanent. If we misuse V1 all the time and start looking for more compression/ glide, what will happen when we get into terrain that truly needs good V1?
