These worms are durable and they are floating, Brandon has worked really hard at finding a substance that will hold the colors he wants, float, have great durability and one that he can run a hole through the center. I've seen a few samples and he's still working with molds to get them just right, they move just as well as any other worm on the market and yes you would be wise to run a bead with them fishing line eventually will cut anything if not bumpered(is this even a word?). Oh and his colors, they are some of the best I have seen.
