I agree with the comment that picks are very personal. Like most of us I have probably tried dozens of picks. I have two plastic bags filled with all sorts of picks. But when I sit down to play now, I am primarily using the Charmed Life brown and black tri's. CLP are now making the black available in a .75. I have 3 brown .75's, 3 1.0 blacks, and now the blacks have become available in .75 so I just ordered 3 of them. The differences for me between the black and the brown are minimal, but I can tell. The browns are somewhat "mellower", and the blacks a little more powerful. Granted, the blacks are 1.0's, so am anxious to tri the .75 blacks that I just ordered. When I want to play REALLY fast strumming I do use a Guitar Moose .50, other than that I have two bags of unused picks! Just my experience, thanks for listening.
