Well, I've been a couple of times in the marshes. Did'nt do much good because of the cold weather both times.From the info I obtained a bass taper flyline is as good as any.With the Reds you are sight fishing so I would image you won't have to shoot a whole line. Especially since it's windy 8 out of 7 days a week down there.A leader that tapers to 0 or 1x should do.We'd make a leader using 25,15 and 10lb line. It seemed to turn over well. You might want to go to 30,20,15 since you are using a 9wt.If you are going for the fish with teeth, that's out of my league.Good Luck and God Bless!
