Done.
>>10559417You'll run out of lifetime to build long before you'll run out of 1/72 kits. That said selection is likely better in 1/48, so the odds of you having this or that specific variant to build would go up a bit there (whereas if you just want a Corsair or a Mustang, well, you'll find that in 1/72 too). For the really niche stuff though I wonder if 1/72 might not have a bit of an advantage, but then we're talking stuff like an MFI-9 rather than a Bearcat.
>since I'd like to have an entire fleet all in the same scale.Perhaps one day you'll want some jets and/or bombers as well...
I went 1/72, but it isn't like there's an obviously right and wrong answer here. (You wouldn't ned to ask if that was the case...)
