I feel your pain. I'd been using bar end shifters and a helmet mounted mirror until recently. I hated the helmet mirror. I tried a ton of different models, and none of them were very good. Horribly geek looking too.

I recently switched over to a Retroshift setup, thus moving my bar end shifters to the brake hoods. Awesome setup. Much better than traditional bar end mounting, if you spend most of your time on the hoods.

So I'm now able to start playing with drop bar end mirrors. I don't hate the Sprintech so far. It does get knocked out of position, but positioning is much more forgiving than my old helmet mirrors. The mirror practically disappears on the bike also.
