For Say true i have player with one of this rubber in january... And for me i feel not problem... Just m'y think IS : important IS need use good white glue and good booster.....
But i think if rubber signature like this IS better for collection than for play...
I not use blue sponge now because for me broke blue sponge rubber IS more easy...
If i training serious and play serious match, 2 week rubber IS dead...
Then i use orange ... With orange i Can use 2 months... Thats better ...
But sometimes orange i broke too... I have vidéo 1 match of me and i broke rubber ( bubble ) on this vidéo at moment WE Can see the bubble on m'y rubber...
This rubber was less 1 month...
If Someone want link of this match i Can Give Link... I have fews matchs uploaded...
M'y level IS not very good, but not Bad...
I Can t talk about ranked there because every country have différent system ranked and level ...
And yes Chen chen Can get true rubber and blade from national team chinese, de talk together sometimes... All he get IS true., And he IS good Guy...
