Sounds like you've already made your decision...
I switched to Holosync (from my own BWgen soundtracks) in November 06, and haven't looked back. Absolutely fantastic experiences from Awakening Prologue, both in meditation and out. In the two-and-a-bit months I've been doing this meditation, I've recorded huge changes in myself, all for the better.
Also the followup materials (a book by Bill Harris, extra CDs for concentration and problem-solving) and the support is great.
Private message me if you'd like specific details (I don't want to soud too much like a commercial here!). It really is an awakening...
