Yeah. There is a thing called the "COM release" in the USSA. I think 300 GS technique and tactics. Where they discuss releasing the COM before the feet, it has some benefits - if the feet are not released yet, you're basically lobbing the COM into the new turn. Could be related to toppling to some extent. There... no toppling, no pushing, no falling - let's call it "lobbing" the body at the next turn.
I have to disagree with you. Perhaps. First, I pretty much always release my CoM before the ski edges are released. Perhaps you should explain what you mean by "release the feet". The CoM pretty much always is released prior to the edges..so... I don't see the relevance here. I guess a cross under style transition might release the ski edges first..but that isn't really what we're talking about here.
The question: is
whether you should go out of balance by allowing your CoM to topple, fall, drop, be thrown or lobbed; to the inside. Counter balancing efforts can be made to avoid such things whenever possible. It goes without saying that there could be extreme situations where ideal balance cannot be maintained due to course set, etc..in which case recovery moves will be imminent...fine...but I see nothing about a CoM release...that means you have to actually "lob" it, other then perhaps extreme situations, which you went on to explain further below.....
Some could "help" the body to move a little faster into the new turn, it usually quickens the turn, as the feet need to come around quicker to catch the thing or boom - the problem is obviously if the COM gets to far ahead of the feet in the GRF direction, you get boom. Or too far inside the turn (i.e. far from the feet), boom. Or faceplant in my case... to each his or her own.
There can obviously be cases where a racer may need to make a radical move, despite some undesirable consequences. That is the whole point of making course sets difficult to force such things. still, they will be compromising high-C engagement and probably compromising engagement in other phases of the turn...and yes they will have to recover from that and yes that will be more difficult and less smooth. All things that recreational skiers don't have to worry about, they can retain engagement, balance, smooth skiing, smooth control, grace and all the rest because no course is forcing them to compromise those things.
Initially TomG came up with the toppling as an aid to get people to move inside the new turn and get bigger angles, as I remember. I certainly prefer to let me feet do the talking... and don't use anything like toppling in instruction... but to each his or her own - maybe it does work in some cases?
The word toppling has been around a lot longer than TomG. He didn't come up with the term. He may have promoted it at some point.
As I already said several days ago, there can be a time and place for using the term, perhaps for someone who is fundamentally blocked from moving across or at the other end, someone who is throwing themselves too aggressively. A stepping stone concept. But I also feel that if left to fester the meme inspires imbalanced skiing, and balance is a sensory thing and a lot of people are skiing around without a well defined feel for what it even means to be in balance on a ski and milking all the goodness out of the ski edge. But hey...knock yourselves out..whatever makes you happy. But if you fall (or lob) away from your edge...you are compromising engagement through some phases of your turn. Might even encounter a snow snake. ;-) May be a suitable compromise in some cases of course, but the
compromise needs to be acknowledged.
