Flies for all, fatman is right on. Pull the inserts and use lighter wire for the mail shaft. I use .024 or .029 as well.
French blades seem to be the easiest spinning, but the Swing blades from Do it or Jann's are a good Rooster Tail type imitation.
Make sure you are using a clevis that corresponds to the size of the blade. Too big of a clevis will allow the blade to tip back towards the body and will cause non spinners.
Another great option for spinner bodies is BTM-5-SA bottom bouncer mold. Here too, oil and pull a pin and you have a nice spinner body. The BTM-5-M makes slightly bigger for Musky Bucktail bodies.
I have also used the WR-9-A worm rig sinker for Panther Martin style spinner bodies for years.
I straighten a paper clip, run it through the hole, powder paint them, and the paper clip hangs in the oven for baking.
