No, I have not yet tried a double jointed snaffle but it is on the top of my list to try. I've been emailing back and forth with the new instructor too and that was the first thing she suggested. She said she may have one for me to borrow in a 5.5". Unfortunately I will have to wait until I start lessons and I wasn't planning on starting lessons again until April. (I'm too impatient to wait that long! Lol)
So far all of you have been super helpful, giving me good critique and info to work with without the nasty undertone. I appreciate it greatly! <3
And yes, the "chicken wings" (or flapping elbows) and the driving with my shoulders are habits my instructor is always trying to break me of. It's terrible I know! It gets worse when I take some time away from lessons and ride on my own for a while. I'm sure I'm horrendous now as I haven't taken a lesson in months! I really need that person standing in the middle of the arena reminding me of all the things I should already know!
