[Unanswered]  According to WBO rules (plastics)

Hello, i don't really know anybody in particular who can answer to this question: so, i basically need to know if a weight disk can be used in reverse (completely flat side of it) in order to keep the sub-ar tighter to the ar. I just checked the WBO official tournaments' rules, but i found nothing at all about this...
To be honest i doubt it would break any rule, it's pretty much preference to what side you put up and I've never seen this topic discussed. So it should be okay
That's 100% correct, but the lack of infos about it makes me feel uncomfortable...
