Humuhumunukunukuapua'a:I wear one. I like it for surface swims, though I switch to my back sometimes too. Other times it's fun to look around on the surface swim.
around here about the only time i look down on the surface swim is to figure out if i've got 5' of viz or 20' of viz. i usually just put my mask on, hold a deep breath, roll over and then roll back. usually not that much to see around here.
otherwise, i'll pop the reg in my mouth at the surface -- even on the move, air consumption should only be around 30 psi/min and i rarely come up with less than around 800 psi anyway...
