Actually one of the first wobble heads I had was a regular slider head that the late Charlie Brewer ( a friend and fellow Fishing Facts writer at the time) sent to me -he had flattened the head & bent up the nose to originally keep it somewhat rock free among deep rocks. Now, the Hawns Jigs version has much better action,especially in stream current, because Keith pours these smaller and in tin ;but ,as he advises, you don't overload this head with too much stuff on the back end.Of course his rapidly-becoming-famous HU head can do the same function,but is more stable over all. My use of a small propeller of the shaft gives a great spoon-like wobble and often has this model head darting downward on the drop, or "cutting out" when given loose line. Here,again, the trick is a light tail - I've even taken to trimming over half the fur off a rabbit or mink strip to provide less resistance and more action (discovering that an almost bare zonker hide yields better undulations than a furry one!!).
By the way, in our 2 member organization, I believe this is actually Keith's year to be president,or the official A.S.S. head!! (guess that puts me at the other end!!!). And,sure, Attica, you are more than welcome in the club!!!
