Hey Alan,
thanks for the link! Lots of good information there, haven't been able to go through all of it yet, but it's bookmarked to keep reading during my practice/learning time tomorrow.
I agree with you, I feel a lot better about string muting now than I was feeling a few days ago, it's still a bit of a challenge and I'm not as "fast" when I try to mute unused strings, but after watching Christopher's beginner videos I can play around with it and even when doing "spider legs" I try to apply those principles, I've found myself doing it without noticing a couple of times while practicing last night.
Thanks again guys for the help!
