Jig mod I’ve been using

I’m sure it’s been done but It’s basically an improvised underspin situation. When you’re jigging it like normal it flashes erratically, but on a slow/medium speed straight retrieve it spins consistently.
It’s easy to do. I just take a clasp/snap swivel and put the larger side just below the skirt. Then put a blade on a split ring on the other side of the swivel. I trim the skirt so it doesn’t interfere with the spin.
Tried my best to photograph it. Cheers!
