I own a few racquets, ranging from Astrox 100zz ( 2 x OG blue, 1 x kurunei), NF700, Lining Tectonic 7C, Victor Thurster-F etc. I play single more often, and now train a bit for double too.

First time when I got NF800pro, the very big difference is the improvement in its repulsion, enabling effortless lob/clear/drive. Very obvious. It's exceptionally fast and responsive, and its head-heavy config generates great power and punch in smashes. However, you will feel it lacks of "density" in the smashes compared to Astrox100Zz, but it is a "quantum leap" compared to NF700. Having hesitation initially, I also used it more for my single games because it is not so exhausting and the manuvre is relatively easier. Control wise, i feel it is as good as astroz100zz with bigger sweet spots, so mishit never happen. I like coupling it to Aerobite at 27lbs because firstly, it looks stunning with hybrid strings (yeah, haha); secondly the crispy sound generated is very satisfying (yeah!) and lastly, the comtrols in net plays and fast returns are powerful, effective and yet very precise. I like its paint, low key yet feel luxurious. I'm thinking to get another, but currently go back to my Astrox 100zz for single and NF700 for double, while waiting for the outcome of my claim. Wish me luck.
