The black ones? I like those too. I'd been using the medium picks that came with Rocksmith, then my friend Zach gave me a bunch of the Dunlops. Very nice, grippy, and for almost a year I used nothing else. Lately I've been switching to lighter and lighter picks, trying to get the right sound on that 70's funk strumming I sometimes attempt. Nowadays the green .88 Tortex are my "heavy" pick.
