I don't quite understand this because I thought ITTF only approves the top sheet for it LARC.cole_ely wrote: on Wednesday July 17,2024 at 8:23 AM
If I put my own sponge on a topsheet, how does that give me an unfair advantage?
How can you check if the sponge is from the manufacturer ir was assemled by the player ?
It may be difficult to do this for an inverted sponge but much easier for any rubber with pips facing out.
