Great all around pick
I play a combination of melody and rhythm mostly in a celtic group. I play an old Guild F48 6 string and a newish Taylor 12 string and more recently an Irish tenor banjo. I have tried all sorts of different picks and have never been satisfied until I tried these. I like a pick with some flexibility for the fast strum of jigs and reels, but really hate the muffled sound of the soft plastic picks. I mostly use a 0.73 mm for guitar and a 0.60 mm for banjo. They give me the drive that I need with fast strums and crisp notes with melody. I have tried other picks with similar characteristics, but they tend to break just as I get into the first reel of a Cape Breton set. I have been using these for several months now and have not broken a pick. This is now my standard flat pick.
Prosflexible, hard plastic gives crisp sound. Unlike many hard plastic picks these seem to be very resistant to breakage.
