Definitely open G (DGDGBD).
I kind of agree with Silly Moustache, it's better to get into the feel of it, and do it your way.
OTOH, you do learn a lot by note-for-note transcription (even if you then go off and adapt it). If I was doing this I'd use my Transcribe software, but - much as I love KJP - I don't have time now. I recommend you download it yourself (free for a month). You won't regret it; you'll never be dependent on half-assed net tab ever again.

(I do still refer to net tab now and then, but only as a double-check; it's often good, but it IS always
incomplete....)
