No concerns.
Air tech doesn't really make them sound like A2. It does lower the output, and for a given pickup, take the extreme humps out of the response. Mushy attack? No sir.
For instance, if you put A2 in a pickup that has the same specs as the 36th bridge, it would be dull sounding with slow attack. The 36th bridge is neither. It has very fast tracking of pick attack and it's tight, but it has a lot more midrange than if you stuck A5 in a pickup like that and didn't have the Air tech involved. See for instance, Duncan Whole Lotta Humbucker, which is bright AF and lacks the vocal mids.
I've used a lot of the air buckers and really like that, and I'm a fast picker so I'm very sensitive to fast attack from a pickup, and generally prefer A5 for that, or at least A4, and really only like A2 in very low winds, 8k or less. Air Classic, 36th, Air Norton (in bridge), Air Zone, all track quickly and do not have mushy A2 low end. Like I said, if you compare a regular Norton or Tone Zone to the air version, the air version lowers output and rounds off the big bumps in frequency, and actually makes the lows tighter IMO because there isn't such a massive hump there like there is on the unaired versions.
