Am I safe?

[Thieflordz5]

On my cube, I have Cube4You sticker logos on my white and black side (I find black much easier than yellow I guess) and I have a competition in a week or so (You can probably see the problem here...)
Since having 2 logos is "illegal" in competitions, I know already that I would have to get a different cube/sticker. Unfortunately for me, All the other cubes with caps that I have are yellow... I also doubt that I can take off the black cap (because the screw is exposed...) and I don't want to ruin the sticker by taking the black center off and replacing it with an extra black...
Can you help me with this? (I also have a speed cubing friend, I MIGHT be able to use his cube, but he has yellow (well no surprise there) and that might mess me up a bit)
Any suggestions?

Ruin the sticker.

Color over the sticker on the black side with a non-permanent marker right before the competition. Rub it off when you get home.

In all honestly, get a black or white sticker and replace one of the logos, or both. I feel no need for any logos on my cubes. It makes it easier when they are blank.
