He may not.....but many people do. WOB, gas density, narcosis...there are several reasons why people so - especially those of us who dove He mixes before CCR. I know, including myself, a whole group of CCR divers that only dive some He in the mix since day 1.I get what your saying but as a new rebreather diver, I don't think DR.Mike is jumping into HE right away.
