RE:Rio line winders
Good topic. I store on the spools, but Al's method sounds better. Bill (see steely pics) uses discarded large wire spools from electrical contractors and gets several on one spool at a large diameter. Each can be wound or unwound easily from the same spool because the big flanges on the ends can be turned quickly like a wheelchair with the hand. They have a thru-hole, etc.
I know some trout guys / firemen who have stored their lines in the hose hanging tower! Now that's extreme.
