So, a bit of news and then into the latest revelations
Gala and I ended up 4th overall for the USDF All Breeds awards for the 4th level MFS, and 23rd overall for 4th level MFS. It was a nice surprise, I didn't even know that we were eligible.
In terms of training, Andrea has been wracking her brains trying to figure out where I'm not quite getting the job done with Gala. Things have been going very well, but she keeps pushing for higher and higher quality. Keep her straight in the changes was a game-changer, but I have her jammed against the hand in the changes, which is not ok. Andrea can do the changes incredibly softly, and can of course change the canter throughout the changes. On the other hand, I set up, get the first one and then pray.

. Ok, maybe it's slightly better than that, but throughout the lines - I start holding, and at the end of the line, I have way more horse in my hand then I should. However, when I go to the pirouettes, everything is soft, light, responsive - basically, everything I want in the rest of the work.
So, what Andrea surmised is that I don't have her off my leg. I have her off the leg in an appropriate manner for a 1st-3rd level horse (which is what I'm used to riding), but it's not at all appropriate for a GP level horse. To show me the difference, Andrea had me work a series of leg yields while I warmed her up long and low. Every time I put my leg on, Gala stiffened and raised her head - it was incredibly eye opening to me to see just how much she was holding in her body. So, when I put my leg back, she moved over - but Andrea wanted her rocketing off my leg and staying soft (that is probably a poor choice of words - there was no running and loss of balance, but at the slightest touch, Gala was expected to move over with alacrity and not push back against me for that half second. When I got that feel, she instantly connected and she felt so malleable, it was such a different feel. So, in the pirouettes, where I KNOW that I need that outside hind to sweep under, I get the response, in the regular work, not so much. We moved into the canter with the same expectations - leg yield and when I asked, she had to move. Again, a very, very different feel.
When we picked her up, I had to keep the feel, so Andrea asked to test in a step or two of walk pirouette and I was shocked at how many times Gala tuned me out. But, the proof was in the pudding, the changes were soft, light, and expressive and I was able to change the canter within the lines. But, now I have to relearn how I'm riding the changes again - I can't keep pushing them through like I am, because when Gala is working like this, it's a soft aid. As a result, I was able to run through the entirety of the I-1 test with zero mistakes - a first for me!! So, I'm excited.
We also had a long conversation about keeping track of the hind ends and connecting the horse through the work. Andrea has been happy with how I'm leaving the horses, but she is now after me to start creating more throughness. It finally dawned on me that the reason she does SO many transitions is because she's putting power in, but keeping the respect to the aids and half halts through the transitions. She told me, you can't have power without respect. This came full circle when I was riding Herbie and Caz and she told me that she has them pushed together a bit more (not from the hand, but from behind with an active hind leg. As I worked through the transitions and hh and asked for more behind, the horses got lighter and lighter, more comfortable and more connected and they rode shorter. Both are quite long through the back and the revelation for me was that even if a horse is long, it doesn't have to ride long.
