    I do not think if makes any difference but if you are going to have to cut a hole, then go for the middle. Not sure how much a draw or draft the 2" exhaust pulls but if it does pull then the center would be a better position. My flat top lid already had the 2" opening as well as the 3/4" one so I had no choice and it seems to draw well.

    I put mine on the outside edge for no other reason than not wanting the condensation from the stack dripping on my purty meat.

    I have one drum with holes around the perimeter ( its a pineapple express)

    I also have another one that I built and I use the bung that came on the lid for it. Both work fine.

    Went with 4 1" exhausts around the preimeter on my UDSs. Works great... Many ways to get the job done.

    Do what you think floats your boat, and then learn to use what you designed.

    You will build another one, and then you'll know exactly what's best for you.
