I have played badminton using AP800 for several years, around 5-8 hours a week. The performance convinced me to be an APACS fan.
Armor power 800 is a great racket. it worth a try. It's fast, good (not excellent) power, robust, good paint, good feeling, excellent for its price.
one question is that it's said head heavy (on the shaft) but in my opinion, it's close to even balance or head light. You should try it before buy it. My feeling about balance-point may not be the same to you. I did not measure it but from specification it's 290mm. Campared to nano pro 9900, 9800, npm, it's hard to say it's head heavy.
I will say it's very good quality and robust. It was hit a lot of times in double games. still alive.
BTW, i string it 23x25, i am a double player, satisfied with the AP800's speed.
