I love the EZ vents. I have pouches with filters, but still use the EZ vents, as the filters get clogged after a day or so and then I need some way to release the gas. Hate opening the tail or "tupperware" ring to do it.
As far as gassy foods, you just have to experiment. I was careful at first, but found that gassy foods really don't make much of a difference for me. My pouch balloons up a bit all the time anyway, and doesn't seem much worse when I eat broccoli, black beans or drink carbonated beverages etc.
Also, I had A LOT of gas pains in the 8 weeks after surgery, but they have gone away now that everything is healed up.
