Just boost it.
This rubber is made to be boosted.
I applied 2 layers of booster and this rubber became a monster in terms of balance of spins and speed.
Highly recommended to boost this rubber!
The other good thing about this rubber is that it forces you to place your feet in a proper position otherwise your balls would be slow and not spinny.
Good for training, I would recommend this for beginners in stead of Tenergy series, which is undoubtedly the most popular rubber for pros.
However, I think this rubber is also tricky rubber to use because of its tackiness.
When I loop or drive, I have to move my forearm very fast.
However, when you can hit balls with your maximum power, your loop and drive will be super spinny and super fast.
Because of its tackiness, it's also good for short games like stops, push and flick.
Overall, I really enjoy playing with this rubber and I think I won't change my FH rubber for a while.
