The slightly lighter head as opposed to my Voltric 80 was really noticeable and the N-90 II definitely felt more manoeuvrable, but still very controlled. I just felt as if it cuts through the air much quicker. Clears were really nice and much easier to play than with my Voltric. The touch with my drop shots was great, especially because it's been the first time so I suppose it'll improve over time. My smashes were really powerful, maybe, but only maybe a bit less than my Voltric, but that's logical since it's not quite as head heavy.

In defence and around the net I usually don't have much problems with my Voltric so I obviously didn't with the N-90 II. The head-heavy balance gives great control whilst still maintaining really good manoeuvrability.

To give you further information, I will compare my N-90 II to 4 other high-end Yonex racquets in terms of various performance aspects (of course this is only my own opinion, so you may feel differently):

• Control: 9/10
• Power: 6/10
• Manoeuvrability: 8.5/10
• Touch: 9/10
• Overall: 8/10

• Armortec 900P:
• Control: 7/10
• Power: 8.5/10
• Manoeuvrability: 6/10
• Touch: 7/10
• Overall: 7/10 

• Nanospeed 9900:
• Control: 7/10
• Power 5/10
• Manoeuvrability: 10/10
• Touch: 8/10
• Overall: 7/10

• Voltric 80:
• Control: 9/10
• Power: 9.5/10
• Manoeuvrability: 8/10
• Touch: 8.5/10
• Overall: 9/10

• Li Ning N-90 II (first impression):
• Control: 9/10
• Power: 9/10
• Manoeuvrability: 9/10
• Touch: 8/10 
• Overall: 9/10

As an offensive player I obviously favor head-heavy racquets but once again this is my point of view, others may find head heavy racquets too tiring too use which is absolutely understandable. But for me, the N-90 II might become my new go-to racquet although I'll need to test it much more before I can decide. But it has impressed me already and I can safely say that it's an awesome racquet. Great control, absolutely powerful, really fast in defence and around the net – it sounds too good to be true, but luckily for me, it isn't ;).
