Fantastic work, I love it. The results I get are sometimes surprising. I play mostly folk, country and blues so it's always surprising how irreverent a lot of pop music is when it comes to progressions. Also, I don't see the "big II" hardly at all. Playing the major II instead of the minor ii is fairly common at jams I've been to but maybe it's because a lot of people don't know minor chords, throw in the major instead and think it sounds good.
