reboost is common.
some times a bad boost job, they will need to reboost.
or need to touch up on a layer.
well, the higher the level we go, the more consistency of rubber performance we need to focus on.
a 1% margin is too high.
A group of elite male players that include one that beat Dima before, all use DHS on forehand (i think except for 2, one using Butterfly and the other Xiom sponsored, but with special harden rubbers)
They tried D05, T05H, D09 etc, when it came out, and the feedback was, the reliability of the rubber when the ball is very low (near touching the ground) and for them to loop the ball back, Butterfly is not good enough, when compared to a DHS H3 provincial blue sponge.
This is just 1 example of where performance comes in where the players tried it, and it just isn't the same.
I think most non pros/non semi pros, won't be pushed into such a position and won't even get the ball back with quality - even with a DHS. But for these guys, they can perform better with H3 and that is why it is a market wide preference. You really need to know how to use it, then you know the value.
Now if D and T family can't do it, how in the world would Yinhe, Sanwei and all other brands that no full time player in China using them? As I said, all these tier 2 brands in China all have good sponsored players, none of them use them....
No offense to these brands, but its just a different ball game. Even 729 has fallen off the bus.
