I modify my jig heads by converting a ballhead into an asprin head using a pair of pliers.
I feel I get a better hold on the flat head.
I also tie shooters with whitetail hair instead of marabou since it is hollow. My thinking is it will fall a little slower. I have been experimenting with glow flashabou since most of my best producing docks are enclosed. Smaller heads are also used alot since they make less of a splash.
