@Robert, at the beginning of your "Mastering the E Minor Pentatonic Scale" video you showed the Farley pick that Vinny had sent you.  It is thick and looks similar to his Screamer, which is, probably, his most famous pick.  In looking at his website and pictures the Farley is perhaps slightly more rounded.

How would you compare them?  I will probably give it a try.  I started, of his picks, with the Screamer and used it for a while.  To try his I bought one of his sample kits. I have settled, for now, on the Tradition Lite.
