Seems to be. Although I do see some on ANG Vipers occasionally. Colorado uses them pretty regularly. A lot of the test and/or training squadron use them, too. When I flew with the 85TES at Eglin, my jet had a -131 pod on it, while one other Viper in the flight had a -184. About half of the Hog units out there use them, too. I wonder why it is so much more common on A-10s?
I think "got right" was a poor choice of words. I should have said "nice additions". The ALE-50 (although it seems too narrow) and calibration chart on the canopy, for example. And Tamiya's incorrect painting guide, which is obviously not a big deal.
