They all just as good but the 5 mm heat element you get a wider seal.

Liz, check out Joe Gargas posting on Aquabid, he uses the breathable bags but it sound like the Discus are only Dime size, this is good for anyone that doesn't an oxygen tank.

Yes, the Discus he sells are tiny and can go in breather bags. I have O2 and feel more comfortable using real bags.
