For my baitcaster/ flippin , casting and pitching
20# Stren Super Braid.
...very skinny 6 pound diameter
... camoflaugh
....cast decent
....does not twist when flipping.
....hasn't broke yet

one draw back..bleaches out so you will need to cut line off periodically.
Lot's of hits during spawning season. Pulled bass out of sticks real good.

The improved clinch {trilene knot} or palamar both work great.
Being that my eye site is going ..Palamar is whatI use mostly.

For my spinning reels I've always used 10 #Trilene. I've tried the others and have gone back to good ole Trilene
