Just something that came up and I solved.  I love the way the original Berkley PowerBait Pit Boss creature bait waves its outer legs when reeled through the water.  It's a great bait that can be moved through the water like a slow moving crankbait. BUT... I happened to buy a bunch of 3rd party "identical" creature baits to save some money and the legs DO NOT make a waving motion at all.  They look exactly the same.  Not the same.  On further analysis the baits made in 'home-made' forms have the thickness of the legs equal all the way from the body to the end of the leg.  An original Pit Boss...the legs are thinner where they connect at the body and fatter down the arm.  This weight difference is what creates the leg motion.  I'm now spending time (which I enjoy because I tinker with lures a lot) adding a bit of soft plastic to each outer leg by melting a rubber worm with a candle and dabbing it on the leg ends.  Motion back!

Interesting. Cool ?
