also trying hard to resist, but.......
Mi 8 instead of 26 (most produced helicopter in the world) or both rather than both S64 and CH47.
B47 deserves it over the Robbo, and
Cobra being the reveloution it created as the first, longest and most produced gunship deserves it over the Apache doesn't it?
Lynx??? Strange one.
Actually, you have a damn good list there, and ANY list will have it's buts and maybes.
