Hi JR!
Have you tried "Mindtek" products (mail me if you can't find it and I'll give you a link)? Frankly, I find their brain entrainment more powerful than the Centerpointe stuff, to feel at any rate. I am in the CP programme on the inner level, by the way. Also, if you are interested in learning I could recomment "accelerated Learning Techniques" by Brian Tracy and Colin Rose. I also have all the "Superlearning" stuff, but I wouldn't recommend it. In my opinion, it's a sham.
