Btw, I did try the Mare's Mid X Vision. It fit well, not perfect, but ok. It hit the brow bone a little bit. Hubby convinced me that if it hit at the surface, that it would really hurt at 90 feet, but with Visulator hitting so hard on the nose on the surface, I think worst case scenerio I can handle a little mask pinch on the brow from the Mare's mask.
No difference in wearing a mask at 5 feet and wearing it at 150 feet. You blow a little air out of your nose, and the mask equalizes the same in both places.
