Folks I know and respect are saying good things about the folks teaching these seminars, but are not saying that they have taken useful stuff out of the seminars and applying the techniques in their own practice.
That's because it can't be done.
Not that there won't be things that you can immediately add on, but basically speaking, this stuff is not an add-on. It's not some extra tricks and twists that you can add on to your regular training and go along on your way.
What we're talking about is a fundamental change in the way that you use and condition your body - that change affects everything else and, eventually, is expressed in the technique (it does take some time).
So...rather than doing an "Aiki technique", you do Aiki and the technique expresses that quality of your body (and mind). If that makes sense...
Best thing is to go try it out! Alan Beebe can't be too far from you, and Dan gets down there.
