Hellbender, I would like to have you along for a trip in my boat when I was targeting the 'Gills. I never use a weighted float, mine are peanut size or smaller. I had a hard time casting a 1/64 and a small float with 4lb and will be using 2lb with a 4lb leader for this next time out. And when a 2lb LMB latches on it just gets that much better. I've tried weighting things down as you spoke of but find them very hard to cast in tight to the cover I fish. Short casts to make a presentation within 6" of a washed out bank and so on. If you ever get this way please holler and we'll go play.
Creativity is just intelligence fooling around
