Great thread. I have been working on this too but with limited success.

So from what I gather by reading this is to open your eustacian tubes so that you hear "regulator breathing" through the tubes. I can do this... its kinda loud. I feel my tubes open more and the breathing sound gets louder when I press my chin against my chest. Then just hold your tubes in this position and your ears should kinda auto equalize (maybe with the help of a forward jaw thrust at times) as you descend?

Perhaps this is what I have been missing. That is positioning my tubes open on the surface before descending.
