I'm answering my own question, how geeky of me.

I think I figured out my problem. The straps are too long to just put the bra on and go, but if I pull down the back of the bra to make it fit a little better on my body, it seems to stay in place better, too. I went for a 2-hour run (jog, but same bounce factor) this weekend after making that adjustment, and I didn't have nearly as much rubbing by the zipper "end" (maybe none, but I still have a spot from before, so it's hard to tell). I do have trouble with my HRM slipping under the bottom rib of the bra, which means HRM rubbing against skin (OW), but I think I just need to be more careful there, too.

I still wish manufacturers would "protect" the inside of the zipper and the base of the zipper a little better... the skin in these places is so sensitive. Kudos to Hind for at least protecting the inside of the zipper itself with a little flap of soft fabric.

I'm still fighting my zippered collar tops. I have yet to find something that zips across the top of my chest (even just a few inches) that doesn't rub from the top of my collarbone down my chest. I think I will consult my Super Sewing (and Cooking, and Cleaning, and anything else) Grandma and see what she thinks about safely making them stop eating my skin; I'm afraid to sew anything into that fabric and ruin it.
