But they've already made drastic alterations to the roundel - the blue circle is thinner and has the True North notch. The maple leaf is very different and mostly covered by a plane (and if we're talking about not messing with symbolism, this would have to be at the top of the Canadian-symbols-not-to-mess-with List). There's already a thin grey outer circle that's not present in the RCAF roundel. So all that stuff is completely fine but if you make that thin outer circle red that's over the line? That makes no sense...
Because it then starts to resemble roundels that are NOT the RCAF.
Personally I wasn't talking about replacing the blue ring with a red one, it's the secondary ring I was referring to. Because the blue ring on the dark jersey is the exact same shade as the jersey itself, it ends up just looking like it has a thin red circle on the outside of the logo. It needs something else to give it some depth, like Mort said maybe a little white outline. Perhaps it's just the picture though, it seems like the ring is part of the jersey when in fact it's part of the cresting on the current jersey. That in itself gives it a different appearance.
I'm not talking about replacing it either. I'm talking about the fact that white / blue / red circles == the US roundel from WWII.
