Just checked their website and they also include a great visual pyramid there with logos and the number of matches played each season by different parts of the pyramid. The big hole in it is that the new WOSL has no logo as yet. Its quite clear from this thread that nobody including me, has thought of this very important issue. So my thought is simple, just take the EOSL change the E to W and change the colour in the logo to something else.
