Just watched Justin Kobylka's latest video and turns out he does press and seal over even egg tub and uses a big fan in his incubator. Also mentioned he never "burps" the egg tubs and leaves the press and seal on until they hatch and has done so for a long time with no problems. So sounds like you will be good either way!
Also, I just bought distilled water jugs from the grocery store to put in my incubator so I can always pull one for the proper temp water if I need to set up an egg tub.
