What is the best size fluke for smallies.

All sizes work. If your predominate bait is small minnows use the smaller size. If you have bigger bait fish use the regular size or the mag size. Try & match the forage size.

Five or Six inch sizes are not too big.

Thx guys I really appreciate the advice.

Match the forage. Early spring the forage is typically medium to small, so I use the super fluke jr and regular fluke on a jig head. Come summer the fish key in on shad, chubs, and bigger over all forage so I use the super fluke. I've even gotten into the smallies using the MAGNUM fluke for pike. In the fall I start downsizing again as the water gets colder and the fish start feeding on smaller shiners again. But these are just guidelines, Ive hit days in the spring right before the spawn when the fish are ravaging chubs up in creeks, and the darker colored super flukes do fantastic.
