Interesting thread.
I was completely against Chinese rubbers because they require constant boosting and full body swing in order to fully utilize their power, which most amateur players can't support.
But just the other day, a friend of mine had a Nittaku Hurricane Pro 3 Turbo Blue on his FH. I tried it and I was really AMAZED: With just a snap of the wrist, it was generating twice the spin my Nittaku G1 was generating.
I made a little research about it and found out that it has a Japanese sponge and Chinese tacky topsheet.
It's main disadvantage though is that it's really heavy, probably one of the heaviest rubbers in the market.
While I didn't have a full practice with it to test its power, block, push etc, I am definitely inclined to buy and have a try with it.
H3N does require boosting, but i feel like most people overestimate how much time and effort it takes to boost. it's really quite a simple process:
1) Open vacuum sealed rubber (10 seconds)
2) remove white protecting sheet off the sponge side (10 seconds)
3) open and apply booster (1-2 minutes tops, honestly I spend more time getting the booster off the brush back into the bottle than I do actually applying the booster to the sponge)
4) wait 24 hours for booster to dry
5) apply second layer of booster (1-2 minutes)
6) wait another 24 hours for second layer to dry
Once you finish these 6 steps, all you have to do is glue and cut your rubber, just like you would any other rubber. Most of the time spend is actually just waiting, which you dont have to sit there and watch the booster dry. you have a whole day to do whatever you want lol. The actual time of effort it takes to boost a brand new rubber takes a total of
4 minutes and 30 seconds.
Also, you don't need a full body swing every time. you just need to engage the rubber. To me. that means using the power from your kinetic chain
, swinging fast, hitting with a slightly more open racket face, and then using the flick of the wrist at the point of contact to control the spin.
btw, i'm curious if a 3 times boosted and 2 times glued H3N weighs close to the nittaku hurricane pro 3 turbo blue. i imagine they have to be pretty close in weight since the booster and glue definitely adds at least several grams of weight to the rubber.
