I have NO Use for them
But seriously, none of the Fly Fisherman I no use them. They were pretty popular in the 60's & 70's, I guess. If you go in any of the Serious Fly Shops, I doubt that you would even see one in their inventory. I only see them at Bass Pro Shop, which too me, is more like the Redneck Fishing Store. JMHO, though. I only fish with Ross Fly Reels, but there are lots of other options that cost less money.
WARNING!!! Fly Fishing is Very Addictive & can get REALLY Expensive Very Quickly!!!
