I like the helmet mount. It takes a little while to adjust to proper position and get used to, but once this is done I find practically zero blind spots. A slight turn of the head covers everything.
I use a CRG Blindsight mirror that is designed for motorcycling. A little on the expensives side, but the optics are very sharp compared to most offered in the cycling market. It can be clamped direct to the bar, which should work for you since the end is not pierced. Just scoot the grip in the needed 10mm.
