coming from someone who has use both TRIGGER ALL THE WAY my old fisher(24") that i had in middle school was a grip shift and i did not like them, always out of adjustment for some reason and shifting when pedaling really hard sucked and with my shifters on my current bike (Shimano XTS) I can fly through the gears almost as fast and there is no accidental shifting which out ways any possitive because shifting under power will tear up a $5000 bike like it will a $75 wallyworld special, its just not a good thing ever.
