If you are going to target NP in the 20"+- range you really don't need anything very sophisticated. They will hit pretty much any lure.
My personal choice for those small NP would be a 3/8 ounce spinner bait on a braided line. NP tend to get hooked in the side of the mouth on a spinner bait which makes the hook removal easier.
A lure with a single hook is in any case the way to go with those 20 inchers. It is no fun removing nine treble hook points from a fish, much less from your hand, arm or neck!
A mouth spreader is indispensable because NP generally refuse to open their mouth without some serious encouragement.
Have FUN!!!
