During the cold water period I have been switching back and forth between a bladebait and a 3/4 ounce football head with a 5" hula grub on it. I work them exactly the same way, just a slight lift and drop all the way back to the boat after a medium to long cast. Still do better on the blade, but some decent ones have come on the jig also. I have not really deciphered under what conditions each works best, or if it even mattered which one I was using at the time.
Jigging spoons are a whole different animal. Those produce best for me when I fish it vertically and violently swing the rod up 6 to 8 feet and let it flutter down. It's almost like a hookset every time you swing up, and it really wears you out after several hours of doing it. There were many tournaments on Lake Erie when I would do that for 8 hours straight. Not sure I could any more. lol
I fish all three on the same rig though, a 7'MH fast with 17 pound flouro.
