Will try to get some pics tomorrow.....and am planning on trying to get some help on the ground, too.
Just went back to look at the video my husband did. Doesn't look like the leg is too far back - but it FEELS WIERD

! Maybe the twist in the saddle is different enuf that between that and the different horsie conformation I'm just having to do some adjusting. Looks better when it feels worse - but horse is going better and my lower leg isn't looking floppy.
I'm having some trouble opening my hip angle...and am also having difficulty w/ getting my foot in the stirrup correctly. If it was sitting across the ball of my foot I'd be ear/hip/heel.....I don't think it's ever been right in these boots - am wearing kind of wierd orthopedic boots, which I only got after my mare started getting really wonky - and I wasn't riding much when she was really bad.
And unfortunately, just did an experiment in the kitchen - and can't get my heels down to save myself if I have much bend in the knee (which no doubt isn't helping any

)
I might just do walk tomorrow and have my 'ground guy' walk along and yell at me to get my leg where it belongs.
