Whats odd is when I saw the title of this thread the racquet that immediately popped into my head was the YTK Rad MP.
To me it has everything you are looking for, the only other racquet close is the a fore mentioned BA98, but I find it highly unlikely that it has more power than the Rad MP, which I found to be very powerful for a 18x20 SP, in fact the only more powerful stick, I've played w/ a closed pattern was the BLX 6.1 95, but that has too much weight for your preference.
So my suggestion is experiment w/ more weight, try making it more HL so you can get more head speed, or more weight at 9&3 and counter balance in the handle.
Lastly try somw different strings, I see that you are using Head RIP control, that is a notoriously low powered string, try out some multi's, or a power poly w/ multi hybrid, such as PS energy or Tourna BHB w/ Quasi-gut or Alpha gut 2K.
