From the AA:
"Slower rate of pressure loss – nitrogen molecules are larger than oxygen molecules (which make up 21% of compressed air)"
Crap you're right. I assumed that because nitrogen has a higher atomic number its molecules would be bigger. They are in fact slightly under 3% smaller.
I still think its a con though
