If you are asking about 2 to 6 oz large buck tail or snapper slapper jigs for red snapper?
I agree, 50 lb mono, maybe 80 lb if Sows are expected.
100 lb or over slows the bite down..But Floro is not required.
If you are asking about, Yellow tail and such FLA fish then yeah floro couldn't hurt.
Back to the TX coast, I've seen Bucktails out fish Bait when covered up with lane and vermillion
snapper with straight mono. Floro sure why not? 30 to 50 lb, Med size spin outfit, ie kingfish rig, 20 to 40 main line,Ande of Big game, small black swivel then 3ft of floro,30 to 50 lb. Toss under hand up current.....
