I don't know what the other sites say to do, this is the best on the net for help with anything Q, hands down, in my opinion. Give the KISS method a try and see if it works for you. People on here have more problems trying to improve what works. Not saying you can't come up with some other design that will work for you.
The thing is actually that I was thinking I was making it SIMPLER than the other designs by drilling 3 of the same type of holes in the side of the barrel. I thought it was harder to remove the bung hole cap (which seems to require a tool I don't have) and then putting a flap on that.
But I will try at least leaving all the top vents open and see if I notice it better. Then maybe I can find something to open this bung hole cap.
