How picky are you about your guitar picks? I've heard a few people say they don't change their guitar pick because they think it'll mess up their technique. Personally, I always randomly use 1.5mm to 2.0mm Dunlop and Clayton standard, Wedge, and Jazz picks. Lately I'm into Dunlop Ultex picks which have a great sound but something about the pock attack still throws me off, and I've been using them for several weeks. Anyway there are some guys who always have 2 or 3 picks specifically for strumming, alternate picking, or whatever.
Do you stick to the same one all the time or have some kind of individual system? What kind of pick do you prefer? Does your muscle memory demand consistency with the same pick?
