Maybe you should try playing Wise A** instead. Just kidding. Now really, I meant it (in my colyum) just get the John Doyle instructional video. I have 2 of them , the DVD is the one I learned most of it from. Plus listening to early Solas stuff a bunch (you get the feel of it that way).
A year and a half ago, Xmas, we were to go to Dayton for a visit with the in-laws and the Denver airport got all snowed up and (fortunately for us) we never even got out of Sacramento. So we went home and then, what do you do? you weren't sposed to be there... so I drank Bailey's and put the Doyle stuff on and learned how to play in drop D. So there you go, that's my method, go for it.
