I only play two songs with a slide, both of which are Zed Leppelin songs, and I use my ring. Pinky just didn't seam right to me. :(

Tip for playing Traveling Riverside Blues, if you ever learn to, or want to learn to. Use a double neck with the twelve string neck set to slide tuning, and the six string neck set standard, and use the standard tuning for the solo, much easier. ;)
