As far as I know you should do the country level course ( but I don't know if that's too easy for you since you have been playing for 8 years ). The country course has some picking stuff like Chat Atkins.
BTW, this is part of the guitar fundamentals course, which are structured and linked videos, as being a whole course.
Country level 1 is here:

Country level 2 is here ( with the Chat Atkins picking ):

I think the entire Country course will benefit you. It will turn you into a picker rather than only a chord strummer.
Let me know if this fits your needs.
Have fun!
