Obviously the vent and therefore the hook were already oriented this way on 18s and it doesn't bother me at all. But the lid is so much bigger on the 22s that you have reach too far down, for me anyway, to get the hook to the bowl.
On top of this, the lid feels much more secure in my hands when hanging on the hook with the old orientation. I think of it like pouring a pitcher of beer. Can you imagine trying to hit your mark if the handle was turned the other way?
