Sorry, I'm not connected with Patrick C, other than a link on my page. But, I do like his approach to "sharing" music knowledge with all.
I'm just tryin to do the same.
When I refer to "shredding", I'm really referring to very fast runs or licks that are attainable by using this fast "down/up" picking style, nothing more. It differs from "frailing" in that you primarily pick single melody notes, not just chord rhythms. The two styles can be mixed in a piece, along with anything else you choose to add.
I don't have any videos...I've searched... and can't find any on the web either using this style, except down/up thumb picking. So I figure, it might be unusual to use index or middle fingers this way... although I'm not sure.
Again, you should simply try it, speed things up, and you'll hear it for yourself.
