I usually bring down three tanks O2, HE and regular air. First I take 1/2 breath of air at 21% then I take a little deeper breath with the HE and then top off with pure O2 depending on my depth so I keep the PP O2 less then 1.4. This seems to be the most versatile way. I can eliminate the 21% at the deepest part of the dive or switch to pure O2 shallow. I have to remember not to breath the O2 first in order to limit explosion potential. :-))
