Hi again JR
Having thought about it, there are two other binaural things you could consider. Not a lot of people know this but Hutchinson has a series of 6 "Megabrain" recordings, but I'm not that impressed and the music is horrible and menacing. I got mine from Lifetools UK - check them out on the net.
Another thing I have heard about are the "Gateway" (nothing to do with the software company) CDs produced by the Monroe institute.
Have you got a mind machine? Thay are supposed to work wonders (like everything else in self help!)
