Buddy,
I've got to dig through my Fly Fisherman magazines to double check, but I'm pretty sure the first Clouser Minnows were tied on Mustad 3906 (may have been the 3906B); whichever, it had a TDE (although with the dumbell eyes tied on top it became a TUE) to impart a jigging action. I've been tying mine for freshwater on the 3366 for a long time, and 3407 for saltwater.
Regards,
Scott
