Is there anything that I can do to make it not as touchy now?
I'm guessing that you understand what these half shifts are about but when you try to do a half shift down from the big ring to align with the larger sprockets/lower gears it drops to the middle ring instead. Yes/No?
Maybe the front derailer just isn't set up properly to make trimming adjustments as front derailer adjustment can be quite finicky. Sometimes I find that I was in the lower trim position all along so what I sometimes do is to trim UP first just to make sure I was in the upper position before trying to trim down.
