I was thinking about jig heads and was wondering about balance. I have been using a center balance bullet jighead .Most jigs are tied on a standard balance round head.A few are made with a round head tied head in front of the eye making it a center balance .Does it make a differance? Why would there be any differance between a round head or a bullet head? Where is the best place to buy GOOD colors of material, mainly marabou?Just some thoughts, thanks guys
