[Mr Gazza]

A little further down the line, the plan is to commission some laser cut vinyl ones. This should do away with the clear border round the present stickers.
Not sure at the moment if a Red centre to the "O" is possible.
The old font is a good call, with the different "O".
These will definitely be more expensive and possibly even need to be pre-ordered, but the colours will be denser and the white will most likely be reflective too.
