My post answered you question about advantages.
Another advantage is that the helair mix can be topped off as the ratio of O2 to N is fixed in air and so the He can be calculated.
The big disadvantage of normoxic helair is that the END will not be shallow for OC at the depths you mention. Unless of course you add O2 which upsets the variables in para two above and negates the comments made in my first post
