Update: I read this a couple weeks ago and decided to give it a try. I've used a thumb pick playing banjo, so it wasn't really a stretch. I'm happy with my progress and have been incorporating using a thumbpick into easier band songs. I'm not happy with the size of the pick. (too small for my thumb, even though it's Dunlop's largest size.) I also wish the pick part was shorter. I'm still getting more of the string than I'd like. Anyway, as time goes on I will use this more and more. It saves me from having to grip the pick, since my tendency is to hold on too tightly sometimes. I used to really dig Johnny Winter, and I remember he uses a thumb pick to good advantage.
