Some of you will disagree with me but the original Do-it round shaky that uses the flat eye hooks with the screw lock is just an awesome head, very simple and it works. I will probably get the Trokar model round head because it uses both flat and vertical eye hooks but more importantly it uses heavy gauge hooks, the flat spot means nothing to me really. I think the stand up presentation is over hyped and the reason I feel that way is I do better with a salt filled finesse worm than I do with the floating style and it is by a lot to the point that I stopped looking for floating style plastics 2 years ago. That said, the shaky heads we all make are as good as any sold commercially.
