I have a nice little assortment of darters and have had pretty good luck with them. I'm sure slipbob would also give some good pointers as I know he swears by them, but here's mine. Don't use swivels, either tie directly to the line or use the no-knot fasteners. When you jig them you don' need to jig them aggressively like a madman. They get plenty good action by just raising them up like you would any other jig. I've had the majority of my strikes on the downward run or while just letting the chubby darter sit above bottom. I never tip mine either. My best results have came with perch color or the LOD's, and the smallest in size (can't rememember the size #'s). Hope this helps.
