Pretty much a matter of bucks, right now. My 3 wt reel is an Abel TR1. The spare spool for it has a class II full sinking line on it, which I really don't want to give up. If I could find another spool for that reel, it would probably cost more than, say, an Orvis BBS1, which is the lightest reel I've found so far as a good match for the T.E. 6' for 2/3. So I'm looking at close to $150, for which I can build that T.E. 9' for 4/5 4 piece, with some nicer components !!
