Buddy i'm dealing with the same thing, once you get used to the sensitivity and stretch (or lack thereof) of braid it is tough to pull a jig through the weeds with the stretch of flouro/mono!
Maxima makes a fluoro that isn't too bad for pitching at 20#.
I don't know if this helps...but before I switch to flouro I will try a heavier jig, the idea is to get a reaction bite where the fish doesn't care about the line. I fish mainly grass. Sometimes this makes a huge difference for me.
