So... I wear out standard picks like no-ones business. I tried going thicker & thicker (don't use anything under 1.00mm these days) and still they become unusable too fast. So recently, I bought an assortment of Horn/Bone picks (between 2.0 & 2.5mm) and even they are wearing faster than I expected... So I've now ordered (hasn't arrived yet) a pick made from petrified wood (@ $12 buck a pop I'm only ordering one until I see how I like it) so I'll see how that does... Anyone else have this same problem? What picks have you found to be the most durable/longest lasting?
