I don't like STI because I get lazy about moving my hands, so my wrists get sore, and once they're sore it's hard to work the soreness out. I haven't tried bar end shifters in years, though I suspect I'd like them pretty well, but didn't vote for them because I haven't tried them-- I'll probably get one of those J-tek shifters one of these days.

Anyway, I voted "other" because I like drop bars with the shifter higher up, which is hard to do. I have my touring bike set up with a Nexus 8-sp hub, so the twist shifter is on a flat bar; I have bar ends to give me the drops, and the brake levers on there. It's not attractive enough to be an ideal solution, but I can ride 140+ miles without wrist pain, so there must be something good about it.
