Dave, I did see yours and was thinking the same thing, I will take a 1" vari bit home tonight and drill some extra holes in it, but only go in about 3/4" to see how she works then.This is the inlet air I chose and it works very well.... the upper air inlet helps to stop recirculating smoke, which is very low on oxygen.... and the 3 holes allows for plenty of air to prevent stale smoke, and allow for moisture removal from the smoker with good air flow...
Thanks,
DS
