I use Bagley's B-flat cranks with the squar bill, and I have the bills break quite a bit. Does anyone know of a supplier that has the circuit board bills pre cut for this bait. Also I've experimented with alternate materials to use. I've made bills out of CDs and was pleased with the action but this material is not very durable either. Last night a made a bill out of a piece of plastic from a plano divider. I 'll be testing tomorrow and will let ya'll know how that works.
