I never liked normal picks but I have tried many thumbpicks and struggled with them all, either too loose, too tight or the wrong angle etc I usually give up after a few go's. I saw Johnny Hiland describe the same problem until he tried the Fred Kelly ones. I agree with him, its still a technique you need to practice but these thumbpicks have a perfect angle which reduces the chance of getting it caught under the string. They also sound good and not too hard sounding they match the finger tip sound great. I am delighted now my Travis picking sounds better than it ever did. If they feel too tight just soak in hot water for a few seconds and put on the thumb and it will reshape nicely to suit you.
