I have my Brown rods spooled up with 20 ff and floroucarbon leaders. Been using it for about 12 seasons or so and never had any more line twist than any other line. It lays on the reel just fine. If you get some line twist from loading it on the reels, same as any other line, just take the snap swivel off and let it out behind the boat at about 5 mph for a few minutes then reel it back on.
This will remove all the line twist. Also keep your swivel free from fleas. If it can't swivel you will get line twist.
Good fishing
