Been doing a little googling on spybaits / screwbaits (old name). One site said they were originally made from plastic minnow baits with the lip removed. Wire hook hangars were pulled and screweyes added for the props. Brought up a lot of balsa handmade cranks also but the prices.
Saw some bass website were guys were talking about how this is nothing new, major US lure companies were doing this around 1900 -1910 but chunkier.
Also saw a youtube video on using them from shore in shallow rocky areas which is what I'm going to do.
May try this too but smaller, should be more snag resistant.
