So, you pulled with the left rein, moving her into a tight circle to the left, and your saddle slipped sideways to the right since your left leg was on her back, right? Hard to imagine how you managed to do that, but without watching it happen I would assume you were not balanced at all and heavily weighted your right side...
Yep. I was just neck reining a gentle left circle, and decided to see how much weight I could shove off her right side.
Um...no. She spooked, exploded, and I pulled left because that is what I always try to do when Mia spooks and explodes in a snaffle. Left is her best turn, and letting her bolt straight in a snaffle causes bad things to follow.
Judging from the gouge marks in the arena, she put a lot of power into that tight turn. When it ended 1.5 circles later, my body was still mostly over her back. Had my weight followed my saddle, I would not have had any choice about dismounting. I would already have fallen off.
However, during the next 20-30 seconds, it became obvious that I would not be able to get the saddle righted, and bad things would have happened if Mia DID bolt from that position. So I bailed. I'm actually proud of Mia for holding her ground that long, because that is a pretty unnatural thing and Mia doesn't like unnatural things. And to hold there seconds after a hard spook means she is learning to hold her place when scared.
OK, we did 1.5 turns before she held her place, but that beats running around the arena with diarrhea squirting out the back. Been there, done that, multiple times.
Moments before the explosion, I was thinking of pulling my feet out and doing some no stirrup work. As it turned out, that probably would have been a bad time to try it...
I was also wearing a sweatshirt when it was 75 deg & sunny, so maybe being an Arizonan wimp helped me yesterday.
