I do know that one Weber vent has 4ea 7/8" holes. I did the math on this and I know the 4ea 7/8" holes is a larger surface area than Norco's suggested 8ea 1/2" holes.

Again I was mistaken. I thought people were using eight 1" holes instead of 1/2". That would be much less. Right now I'm just toying with the idea of weber 2 vents.
