The only thing that jumped out at me in the first video is your hands at the trot. Your horse looks like he wants to soften to the bit, but your hands are not consistent. Your elbows are locked or stiff and the reins are moving up and down with each stride. I know you said you've worked all that stuff out, but these are the videos we have to go on.
Phoebe, I think HITS is in Ohio somewhere. Looks like this show was in NH. Would be funny though.
