Thank you for sharing the great idea, Dave.
I'd like to add a small one to yours.
First, thin circuit board lips are more flexible than the thick lexan lips.
So, when we retrieve a crankbait, the thin circuit board lip is twisted to one side (right or left) by the pressure of the water.
Then the twist of the lip turns back to the original state, and ths moves the crankbait waggle faster.
This process will occur continuously every times the crankbait swim to one side (right or left).
Sorry for my long absence and poor English.
