I played that solo for hours until i went into a trance i think. The next mornin' the double stops did'nt seem as difficult. As far as the alternating play, it is just more fun to play that way sometimes, although i guess it changes the expressive feel of the song. Anyway i'll keep working on it. I think next up will be ''Folsum Prison Blues'' for me. It looks like fun also....Thanks my friend.
