If I'm fishing a wider body, say the Lehigh, I like gossamer braids because I can cast 1/12 and 1/7 oz spinners farther than with mono or fluorocarbon of a comparable break strength.
In those situations, I actually use yellow braid, but I keep a black sharpie handy to color the last few feet of line to the lure.
That's also a situation with generally tanic water, and I'm pick-pocketing the breaks in the turbulence, so that probably limits my line being seen as well.
This combo works well when I'm targeting summer smallies in the creeks and the Susky also.
For bait presentations, I keep to fluorocarbon.
