Well I ordered a Stonfo and really like it. It is comfortable in my hand. The tension adjustment is easier than on the Rite bobbin (I still like the Rite bobbin). At Caddis Fly Shop Stonfos are only $19.95 (Cheaper than a lot of the old style ceramic bobbins). Since the spool is a little wider then the tension adjustment nob the little notch in the spool can hold the thread out of the way while remaining threaded which keeps the thread from getting caught in something else or from slipping out of the thread tube, not a huge advantage, but I like it. It is made in Itally of precise craftmenship like fine Itallian sports cars. The thread to is not ceramic, but it is coated with a space age material that is claimed to be more impervious to grooving even than ceramic, it feels, good in hand. The only negative it only comes in Italian sports car red, but I happen to like red sports cars and bobbins apparently.
P.S. why the color changes on the forum I don't like it.
