Roc have you tried to put rattles in your plugs? I have not seen any striper lures with rattles but I have for every other type of fishing. Do you think the wood would deaden the sound or vibration.
You could drill behind the belly hook place the rattle then seal it with putty. If drilled sideways the action of the tail would allow the rattle to work. Since I have never built a plug I may be talking out of my ass but I thought I would just throw this out.
The worst day of fishing is better than the best day at work.
