Hmm, that is awesome. Yea I was going thru all of mine and was like I should try and replicate this spinnerbait. I like the flex arm design because u can bring it to the surface and the let it fall and wham they get it everytime. I used to use it like a topwater too and let the blade just break the surface and then let it fall, that flex arm really gives it a good action. It looked like a simple design to make but wasn't for sure of how long and expensive it would be. Good info to know.
Thanks,
