Silly thread. I have two DIR rigs, and two jacket style rigs. The DIR rigs are for diving with my team style diving escapades. The jackets are for DiveMaster work. My Zeagle Ranger has had an Air2 on it since 1996. I've used it in an out of air emergency, and it works just fine.
Bottom line- it's not an issue. If you don't like the Air2, you really shouldn't use it. If you like the idea, then train with it and enjoy. It works just fine.
