I used my Alasks Pics all through Bishops Castle Folk weekend and am now finding that I can keep them on for some more complex accompaniments. I'm delighted with them. The only thing I wonder about is whether they go big enough for guitarists with larger hands. I've got fairly small hands. I ordered small, medium and large. I found I needed medium on my fingers and large on my thumb.Some of my male friends have tried them and found even the large one too small for their fingers. I know there's an extra large size but I doubt that this would be big enough for a thumb pick for some men. However, anyone else out there who uses fingerstyle and has nail problems, do try them. They've relieved the wear and tear on my nails terrifically. Glad they've helped you too Betsy.
