Round holes are fine but aren't good for controlling flow. A slot will provide better control. 3/8" to 1/2" wide slot 3" long with a sliding door ( like above ) will give a consistant air flow change with a change in door position. Moving the door a 1/4 inch will change the air flow the same amount whether it's half open or a fourth open. I believe this will make temp control more consistant time after time. And if you mark the door and or slot, your postion will be easier to find after shutting it to open the lid or if it gets knocked out of position accidentally. I want mine out of the way so it won't get changed by someone walking past and hitting the valve. The throttle cable controller will work great with a slotted door. Just my two cents on air flow.
