Howdy,
I let the water depth and temp. make the call. Waist deep ( 3ft.) is the setting I use most commonly. If the water is deep enough and I'm not getting strikes, I'll set it chest deep. An occasional take down on a rock is o.k., but I'll reset shallower to avoid this. (when my bobber goes down I want to know its a fish) I don't fish deeper than 6 or 7ft. then I think the drift gear is more effective. Purple, pink/white, and orange/yellow jigs with a chunk of shrimp. Remember C&R and they'll be waiting for you next time!
