I squeeze hooks in all kinds of jig molds to move the eye placement. It changes the action by moving the eye placement. If I get one I really like I will mark it and drill a permanent location for the hook.
I have tried all kinds of blade heads. Most work, but aren't much different than the original. I do have another one which I will photo and post. I call it the "3/4 Fatty". Its the head from the 3/4 oz "C" spinnerbait mold. If you want a blade you can just rear back and launch off a breakwall 200 feet and crank it back it 15-18 feet deep, this is the one!
I have another one that I make using the slide-along head. You can fish it really slow.
I'll post some pictures.
