As the OP, I would like to move away from whether it is ok to squeeze a bag or not. There are plenty of other threads to debate that. After 6 years of brewing, I am comfortable squeezing the bag. With that, maybe I need to do a couple identical brews and really focus on the effeciency difference in squeezing and dripping. I double batch sparge so considering that, maybe whatever is left after dripping is insignificant.
Captain, I think you bring up a good point about the risk of infection of a press as you can't clean it the same way you can a brew pot.
