This is my take on the ?....I use different style heads at different times in different situations....I mean a standard roundhead has been the norm for years....and still is....then there is the pill/aspirin head....it is good in current situations and on a yoyo pattern as they dont fall straight down but go from side to side in a rocking motion...darter head....cuts swift water well and is a good head for trolling or a fast retrieve...then you have the weight forwards that make the baits nose dive....good in standing timber when they are in deep water along the base of the trees.....you also have the minnow heads that not only look good but make baits and jigs look more natural...and then there are the weedless varieties of all of the above.....and thats another chapter....lol..this list is endless..but again this is just my two cents....lol...
