I think the sonic access program will be perfect for you as it offers so many different opportunities for shift and change and it's really powerful stuff. It makes you feel good too! You could use any one of the CD's at different times depending on what you particularly want to work on at the time.
I reckon if you've already invested in this program you should work with it for a little while before adding anything - like I said it's powerful stuff.
Cheers
