Hi Bruce,

Welcome to Guitar Tricks, that's a valid question and I'm not sure how to answer it myself but I would recommend going to 'Full Access Subscriber Forums' under 'Ask _________' and pick out an instructor or 2 that you feel comfortable with and ask them directly, I'm sure they'd be more than happy to give you their insight. :)
I will pass this on to one of our instructors in the meantime.
