Try the Rio lines. Said to be a sponser here. I have an 8wt that I use in the rivers out here. They now come with 4 sink tips Intermediate,types 3,6,and 8 and a floater. the loops are small so you don't even feel them going thru the guides. If you go to their web site they will even tell you how or what to use them on. Much eaisier than having that many spools. But this is just the opinion of an old man.
