Well I think you are digging too much in this theory. i for example don't even know all the names of all the modes but I can figure out how to build them. I think that it is beast to try everything you could possibly imagine when you are practicing improvisation without bothereing if it's right or wrong, just trusting your instincts. It is good to have knowledge in theory but I don;t see any sense of digging that much in it if you are not doing symphonies and stuff like that. The beuty of rock music is that it is not logical. Let's say for example nirvana -- a total rape of music theory See About A Girl
First it goes Em, G Em G etc and than I can't see according to which of the modal rules in the chorus it shifts to C# G# F# E A C but it still sounds great, right?
