Grip vs Triggers

[TsPoet]

Can't stand twist shifters. They are hard on my wrists, I have to move my hands away from a comfortable position on the HB to use them, and they are extra hard to use with sweaty hands.
Just another point of view
I have paul thumbies on 1 bike (replacement for twisties, but I honestly don't have the bike yet, so don't know what I think of them), rapid fires on another (replacement for the twisties when I couldn't take it any more), and bar ends on my last bike. I like the bar ends the best. None of these are mt bikes, I don't ride them anymore, I'm too old and boring now. But, I had rapid fires on my Mt bike and loved them over the twisties they replaced.
On a mt bike, I'd go with rapid fires (do they still make them?).
