Well Having done this for a while, the jury is still out. In my opinion this is soft plastic. I am not a fan of soft plastic. I poured 4 oz to make legs for my Thumper. The legs look like they have no bones. Limp as a wet noodle. Next is field testing how they handle hooks and catches. Now this product may be great for the action parts of jigs, but I have concerns as to the toughness for using it in the body of jigs and how many crappie you could catch one one bait without having to reload with a new one. Will let you know how I make progress after I am back in production.
