1. Chinese would remain better with all tensors as well. Just because of bigger selection base, higher motivation and more intense trainings. Chinese rubbers usually are kind of die or adapt style.I think you're being sarcastic but honestly it is a pretty good idea. Chinese players learn how to play with dead sticky non-tensor rubbers, and Chinese players are the best in the world.
Deadness will teach the beginner to generate their own power using the legs and hips, rather than relying on the tension. It also gives a greater degree of control.
Friendship Battle II is the ideal rubber for beginners imo. Either that or Hurricane 3-50 / 8 / 8-80. Not too heavy, not too dead, but dead enough to teach the player to generate their own power.
2. Using a tacky rubber on BH is not very old idea. It's pointless to compare CNT members with an average beginner. Moreover heavier setup brings more injury risks, especially if you are not so young.
3. China can easily replace an injured player or one who does not keep up, but can you replace yourself? I have experience of injuries and switching to left hand, it's not fun at all.
Basically at beginner amateur level all comparisons with top pros are simply irrelevant.
