Blue Sponge!

why are there yellow shoes?

blue sponge can only be used under black topsheet. Some sort of coloring regulation, aka rubber dress code

What`s your point?

Is 729-2 a translucent red covering?

I find the blue sponge seems to be a little softer and more lively than the orange sponge.

That may be true , but if all coverings are translucent there would be no need for the ittf to use the word in the description, or so it would seem.

Assuming what sunflex wrote is correct, why would a provincial team member have illegal national team rubber sheets, maybe provincial and national  team members who use 729 products do not play outside of China? 
Maybe she gave them away now that she is playing in Holland?

Another case of confusing wording in ittf law. 

I would guess that maybe some black sheets are not translucent, so they decided to use the word for both colors?
This still doesn't resolve the case of Li Jiao's rubber sheet, so the apparent mystery remains.

Maybe that's why li jiao gave it away! :)  Or maybe she had the sponge but the guy wanted red topsheet, so she just put it on there for him.

the blue sponge it's softer than the regular ones.
that is what a lot of chinese players claim.

you just can't use a red topsheet without a sponge (ox) on ur boll carbon. The rule doesn't say you cannot put a topsheet + sponge on ur boll carbon. All the rules are needed, otherwise they wouldn't exist.

Come now Thomas, it's not like you've never overpaid for blue sponge before.

I guess maybe now you've learned your lesson.

hence i'm trying to reearn the amount i overpaid xD jkjk
