Isn't it advisable to play with a 3U head heavy racket in such conditions?. To use a little more brute force when an even-balanced/head light racket just doesn't cut it for the night. I noticed ZF2 is a popular racket in the Place B. It seems to be on the stiffer side with a smaller frame though.
Have tried quite a number of rackets including 88D, 88S, 99, and 100 both original and Pro versions. I thought that head heavy rackets would suit me better because I enjoy smashing, but in the end I found that I smash harder and more comfortably with my 3U BS12. Perhaps worth trying a different string. I use Aerosonic which may be a slightly harder string compared to say BG66 Ultimax (although it's not a hard string like BG80) and is a very repulsive string.
