I'm interested in making my own soft plastics...mainly worms, flukes and lizards for my own use. I'd like to use one piece molds so I can use different colors on tails, and other appendages but I'm concerned about the "flat spot" that one piece molds produce. How much of a flat spot will a worm have? Can someone post a good picture of it or post a link to one? I'm sure a hungry fish will not mind if the worm is not completely round, I'm just wondering what quality to expect from a one piece mold. Would I be able to make a worm with a different color curly tail on a two piece mold? Thanks for your help.
