The idea is obviously not new, but it is a good one. I have experimented with this type of application and it indeed works well. It is a difficult lure to produce, but the action is very fluid. I have a concept bait that I played around with a while back, and decided to top shelf it until right time had come. It was developed with a kevlar strip, threw a three piece lure. Worked great, and swam well, but the issues with the epoxy getting into the fibbers, or compromising the linear strength was an issue at the time. I have talked to many Kevlar manufactures and have tested out many different materials, and am still confidant that it will have it's time and place in the market here soon. By the way, Hazmail is right, and rubber or plastic material will indeed go bad in time, or dry out and crack!
LILI Man!
