Thank you Laminar. "Circular equalizing" is definitely the way to go. I mean, the mouthfill is so relaxing, why not using it from the surface already ? And the focal points also should help a lot in refining the techniques.
But I'd like to share what I found really helped me so far. I waited until I went diving 2 times before replying, just to make sure. It is the ballon exercise Scorp pointed out to us, which is described in
The Frenzel Technique :: FDTF :: Freediving Team of Finland
What I do is I use 2 or 3 very forced exhales to fill the balloon (so I train my diafhragm at the same time...) then do the excersice described above maintaing the last forceful exhale. It kinds of recreate conditions at depth to be able to keep the epiglottis closed for a long time (well, maybe 40 seconds...) in spite of the strong negative pressure in the lungs created by the exhale, while at the same time you need to keep the soft palate neutral otherwise the air from the balloon will not exit through your nose. I actually play with the soft palate as well during the exercise, repeatedly stopping the flow of air from the ballon to my nose (like an on-off switch).
Well, I did that a couple of times during the past 2 weeks, and when I went diving things worked much better. It is actually now much more clear to me that the epiglottis is way down your throath, and far away from the soft palate, which I now can clearly notice it is basically at the back of my nose.
I think we're on to something here...
Cheers.
