netg, thanks for the photos! You put the chestnut’s pics in my thread about the neck too, and they’re an excellent illustration of both concepts.
kashmere, my horse sounds a lot like yours. (And a $700 craigslist Tb, although not OT.) He’s in an especially silly/spooky phase right now, and I’m learning the extent to which his energy can be managed before he jumps out of his skin just by committing to staying upright in my position with leg on. Done right, the spooky energy turns into a bold approach to whatever it was that was scaring him. If I pinch with my knee or pitch forward ever so slightly when he starts to balk, it amplifies his nerves. It’s actually relatively out character for him to be very reactive, but he’s had a lot of changes this year which have probably added up to not enough mental stimulation lately.
Scribbler, your (and Mondo’s) take is interesting. I hadn’t considered that grinding might be a misinterpretation of this phrase (which sounds like it’s being read as “ride from YOUR behind”), but I can see how that might happen. In general, people can go overboard using any maxim and end up doing funny things to their position. Guilty of it myself, in just about every way imaginable.
LilyandBaron, I have the opposite history, but think I’ve ended up in roughly the same place as you. Spent many years fiddling with minutae in the name of suppleness and flexion to the detriment of all forward motion. Now, if I concentrate on forward and straight instead, the soft and flexible seem to come for free — once the jaw unlocks, that is, so I agree totally with you on that critical point! For me it was important to learn how to do that unlocking with relatively passive aids – the driving aid being the only active one. Separation of the aids, which you also mention, being the key for “passive” to be neither restrictive nor ineffective…
