I've been watching a lot of his stuff lately as I've been listening to EJ as much now as I did when I was 11 back in the 90's. I've found I'm too far into my habits to really change my picking style that much. To add, I always start with an upstroke, something my uncle always told me would be a detriment at some point in my playing....turns out it's solved a lot of issues before I even ran into them. The whole 'inside the strings' picking thing has never been an issue, I alternate pick everything and don't seem to have any issues moving from string to string.
Getting the EJ 5-note patterns down has been good fun in the last few weeks as that's such a huge part of his phrasing. I never figured out much of it when I was 11, but having the technical ability some 25 years later is pretty liberating. Hopefully building an EJ/Gilmour inspired rig this year so I really can't wait to start working on that violin tone and busting those out!
