i can never remember the name of that chord i just know the shape and that its root b3 b5 b7. but i am glad to see that the restv of the stuff i said was correct cos i sorta worked it out on my own.

as to the theory being relly complicated, it is when you first see it but its also really logical, at least to me, so after ypou see the patern it all start to make sense. although implementing it is much harder.

anyway glad i could be of help.
