I am not looking to get to another inside tipping discussion again, but just to clarify this little notion - what is exactly sequential tipping and why?
Its an interesting question. There is sometimes talk about the virtues of parallel shins, or simultaneous edge change, yet...is that really such an important thing? We have seen various videos and pictures shared where non-simultaneous edge changes were happening and not consistently one before the other, and yet functional.
What I would suggest is that this outcome of simultaneous edge change is a moot point. I think some amount of obsession on that idea of simultaneous edge change comes from seeing learning skiers struggle with releasing their down hill leg and ski. This causes a wedge entry to happen. That is clearly not a simultaneous edge change, its clearly sequential, but also very much less functional then say the Ted Ligety video that was shared on the other thread. Why less functional? because the release didn't happen in time, or perhaps at all for the learning skier, while the release did happen for Ted. Ted makes the release happen by lightening and relaxing, even sometimes lifting his downhill leg/ski. The learning skier is still standing on the downhill ski to some degree, is not lightening it or releasing pressure from it, nor clearing that leg out of the way for crossover.
So while visually we see something similar between a learning skier and Ted in terms of some short period of time with some A framiness, Ted is not standing on both BTE's at the same time..that is the difference.
I think some people start to obsess about simultaneous edge change because in their view that is how to release the downhill ski and correct the problem in a learning skier that is blocking their release. But the downhill ski can be released by simply relaxing the leg, lightening the ski, sometimes even lifting the ski if you feel like it. Flexing the downhill leg, as LF and others have described, helps to also clear that leg out of the way so that the hip can crossover, while contributing to relaxing it and releasing pressure from it.
I do not like any focus at all on whether the edge change is simultaneous or sequential. The reason is because I see the roles of the two legs as being different. If you obsess over sequencing of the edge change, then one of the legs will forget its true role. I see releasing and tipping of the inside ski as being the primary movement that the brain and muscles should be focused on achieving. I see tipping of the outside leg as an OUTCOME of other things, and not a direct muscle driven movement by the skier. The outside leg needs to be concerned about balance, pressure and stacking(basically standing on it). Turn forces and a proper release, and inside leg action too, will cause the outside leg to tip as an outcome of crossover.
An outside observer may watch and see both legs tipping over and think "hmm, just tip both legs together". But when a skier gets into that mindset, the real role of the outside leg is forgotten, which is to develop balance, pressure and stacking on it, while deferring the other movements and turn dynamics to create an outcome of tipping over on that leg. This instruction of striving for simultaneous edge change will likely lead to negative movements on the outside leg such as knee dive, lost stacking, stems and other nasties. Not that an outcome of simultaneous edge change is bad! It can be fine, but its not strictly essential and the mere mental focus of trying to achieve it will likely lead to unintended negative consequences on the outside leg as I just described.
So if someone focuses on releasing and tipping the inside leg, while thinking about standing on the outside leg, will that result in sequential or simultaneous edge changes? Answer = YES.
My view is that focus on the inside leg should be releasing and tipping it. Focus on the outside leg should be standing on it. Chances are high that if your inside leg release is deficient, then there will be a sequential edge change, but not necessarily. Chances are good that if your inside leg release and tipping action is happening correctly, the edge change may be simultaneous, but not necessarily. Chances are high that if you focus your mind on simultaneous, then other bad things will quite likely happen because the outside leg will forget its primary responsibility.
Much ado has been made about nothing on the other thread about what should be first before the other. This has been confused by language about "leading the tipping", etc. Also that discussion conflated the two separate movements of releasing and tipping.
In my view things can and should happen simultaneously often, but one leg is doing a different action then the other leg, in terms of what we are trying to do with muscle movements, while visible outcomes may show parallel shins...or not... Its kind of a moot point...you have to look way past that to the important roles each ski and body part are supposed to be doing, and are they doing it. The mantra: Transfer, Release, Engage, is not a bad one. Follow that model and the sequentialness or simultaneousness, will not be too relevant.
