Laminar, thanks for the Pressure/De-Pressure exercise. I did it a little bit and I can get both to got each direction with my nose pinched and using frenzel. I figure I'll do that some and "work" the e-tubes and try to get to the hands free. I have not read the document yet either. I downloaded it at work and did again just now.
I have a lot of dry training to do, stuck here in the middle of Illinois with no other freedivers
Maybe I'll work on the US static record LOL. Keep the good info rolling guys.
