412Baitco - My thoughts - A 20 cavity mold for the tail will still not use much plastic and would allow you to get tails done quicker and the possibly several different " body" colors with the same tip color. I know the cost of a 20 cavity mold would be more; but I would think the cost per cavity of the mold would be less per cavity. For that size a "bait"; once you get over the initial cost of the mold

; the upsides are good. As in the claw tip mold for the Mudbug One injection of the tip mold gets tips for four mud bugs

and better plastic efficiency
