yomar:My main problem before was the use of my hands underwater. After watching some videos, I found out that I had this tendency to use my hands to move underwater.
I still have that problem! Old habits die hard.
I'm pretty much the same as yomar, 55mins with 1000psi. I'm trying to push 60 mins but so far all the DMs I've been with have a lower SAC than me. I'll try the palate thing and see how it goes.
