Kevin, Seaguar AbrazX is (IMO) the very best for leaders, but can be a little stiff on the reel. On my reels with fluoro, I strictly use Seaguar Red Label, 12 lb., 15 lb., and 20 lb....Red Label is good all-around line, not extreme in any aspect, good price. My main Bass rod has the 15 on the reel...I have hit some heavy fish very hard and the 15 delivered the BoLo like a champ.
My #1 suggestion for leaders...AbrazX...hands down.
