but doesn't the displacement method mean that you have to keep the zipped end out of the water to avoid water getting into the bag?
I should add that except for very long cooks, I generally use ziplock freezer bags. Like Kayb said, it is just easier not to have to pull out the foodsaver. I don't actually know that ziplocks wouldn't work for a long cook, but for a big 72 hour brisket I am not going to take the chance. In any case, I generally keep the zipped end out of the water, but that isn't hard to do. I use big binder clips to hold the bags to the side of the bath.
