OK tried C-1 and it's much better than G-1 for BH.I've received Nittaku Acoustic just recently (again...), but this time with large handle and this was the best purchase in my life. Feels MUCH better than regular handle.
Nittaku FastArc G-1 on FH somehow fits Acoustic just right. It feels right. It does just everything how I expect it to do.
BH is still under question, though. G-1 is a bit too hard and spin sensitive (yes, this is my personal opinion - G-1 IS spin sensitive when playing against really heavy top spins, unlike H3 or regular ESN rubber like Rasanter or even Tenergy 05).
Want to try C-1 for BH.
The sponge is softer, while topsheet remains very grippy, so I can execute the same BH flicks.
Blocks and counter topspins are easier to execute.
So far happy with this rubber on the BH, waiting when EJ virus strikes again.
Also gonna return to h3 on the FH since G-1 just can't replace it unfortunately. Ordered prov. H3 neo.
