Do-It's 1.5" Thump-It mold is the cat's meow of small paddletails. The webbing between the body and tail button is much thinner than the one shown in the inset and the tail button itself is much thinner than that of the inset. I've tried several different, but similar, molds for paddletails and Do-It has a well defined ring around that 1.5" market, hands down.
Do-It's Thumper Swim Fry might be one to try in lieu of those other 4. Another very productive bait. Very similar, but different in the tail.
