A couple side comments:
1) I have always boosted my hurricane. I think it should be boosted.
2) I have always orange sponge commercial. One day when I stop EJ'ing, I want to get blue sponge, one sheet to just try it out. TT11 did a Youtube vidoe and half of the testers liked blue sponge better but the other half of the testers did not feel a difference.
3) I agree with the other poster. Why not get a sheet of orange sponge and a sheet of blue sponge, and compare it yourself.
4) Other than Liang, don't some women national team players play with orange sponge? Men's players almost all play with blue sponge. And don't forget. Just because it works for a Chinese national team player, it does not mean it works for us, mere mortals. We might not have the physique to unlock the power of Provincial or National hurricane, blue sponge.
5) Finally, a semi serious thought. If you have contact, ask for some used rubbers. I am sure that when they get provincial or national hurricane, they come good straight out of the package. I have always needed at least two weeks to physically break my hurricane in. I cannot imagine Ma Long or Fan Zhendong waste two weeks to break any rubber in. But when the rubbers are broken into and boosted with one more layer, it plays wonderfully. If you have the connection, why not get some provincial versions that are brand new with original packaging and get some rubbers that are used (I assume they might give them to you for free at this point), and try both?
