I'm playing with the HPS 5.0s balanced (13.3 oz. / 10 points HL) now and have had a hard time finding anything newer that i really feel comfortable playing with as well. I really enjoyed the solid plow through feel of the 5.0s but have for the last year or so been looking to tame the power a bit. The modern rackets that I have found playable are:
Prince Diablo XP MP
(smaller sweetspot, more balance response overall than the HPS 5.0, if it wasn't so ugly i might have swithed, japanese site has it in a decent paintjob)
Bablolat Pure Drive+ Roddick
(slightly less control, more powerful, larger sweetspot than the HPS 5.0)
ncode 6.1 95 16x18
(slightly less power, slightly more spin than the HPS 5.0)
Prince Shark MP Std
(slightly more control, slightly less spin than the HPS5.0)
The number os the HPS 5.0 are hard to match these days but those are the rackets i've found to have similar playability.
