I've tried them with bucktail, marabou, unique hair, and super hair. Naturally the two synthetic materials are more durable, but for the most part I stick with bucktail. I've not really seen a difference in success between any of the materials.
For a change of pace, do a search in the Striper Archive for "Deep Eel". This is a pattern developed by Juro for stripers, but downsized a tad it has worked for me on smallies.
