I bought some brass "Alaska" pics for my index and middle fingers. I fitted them on. Wrapped some athletic tape around them and tested them out last night at the luau. They worked very well until they loosened up and started shifting around. I'm convinced, nothing is better than natural fingernails. The brass pics do look very nice though.
Only problem with Alska picks is you STILL have to have SOME nail for them to work. I have been a nailbiter all my life...just nothing there to "anchor" them on if you know what I mean.
