Bought one just like this the other day for a couple dollars at a garage sale. Rigged it up and put it on an okuma celilo rod and let my daughter fish with it yesterday and it was smooth as butter. LOL. She could cast it excellent and loved it. First time I have used one of the underspin trigger reels.
