The idea was to come up with a curly tail grub you could flip in heavy cover with out constantly losing tails to stem wrap. The tail is thicker and more tapered than the average grub, but still does move when falling. The body of the grub is wider along the horizontal axis to help with hook position on the hookset, and the flaps should help deflect the tail away from stems. This is the mold. See Flipping Grub for an image of the mold. I'm debating making a tail mold for this bait. I may redo the mold though as the curve of the tail is not as smooth as I would like.
