that is right, it was only lead-computational for the A2A mode. Such sights were also available on some late-war British (the K-14 was based from a British design after all) and German aircraft, but I don't think the Japanese ever had one. As noted, not having these sights is a choice of the AH developers so asking for them would be pointless as their omission is deliberate.
What WOULD be nice would be an ability to change sights in-flight (I assume you can't do this in AH2, haven't actually tried it yet). There were some very nice A2G sights that some players had made, but they were invariably badly cluttered for air-to-air work. Likewise, the A2A sights I favored tended to be useless for A2G, not that I personally dropped many bombs (I think I carried bombs in a fighter maybe 5 times ever, if that).
Yeah good to see you're still around Westy. I tend to not post much when I'm not active and have never been a fan of making a "noisy exit" so I just sort of disappear when I'm inactive. Currently I'm debating whether AH2 might be worth trying--with (apparently) no porkable fuel and no night-time in the MA, I'm leaning towards trying it as those were two of my bigger gripes.
