Your reference to the infamous "I am Canadian" beer commercial.. 
BTW, fellow Canuck, I tend to agree about the Nitrox. (With you too, Mario.) I just find that in drysuit temps that working with students seems to be less tiring with Nitrox. Esp now that the number of training dives has been increased from 2 to 3 dives per day.
The first time I did it I was totally drained. Next time I did it with nitrox and was pleasantly aware of a difference... still alive, eh?!
