My doubles partner was playing with this exact setup: Carbonado 190 with Mantra H max on both sides. It is a stiff racket and the ball tends to come across very fast, but with a flat trajectory. The stiff blade combined with stiff rubbers makes the racket bouncy and the control game difficult.
He recently switched to a PP Moby (Pro Pro brand made in Taiwan
http://ww3.ping-pong.tw/product_info.php?cPath=24_173&products_id=5398, ~ US$128) single ply 9.2 mm thick Kiso Hinoki blade, still using Mantra H on both sides. It is amazing how the same FH or BH drives would come across now with a nice arc, fast topspin, AND even faster speed. So it is totally the effect of the blade. Moreover, he said that with the softer, more flexible blade he can "feel" the ball much better now. His control (short game, over the table pushes, chops, blocks, etc.) is also much improved.
Our analysis (guess) is that the stiff rubber paired with a softer, more flexible blade is just the right combination for a racket.
So my suggestion is instead of switching to another carbon fiber blade, try an all wood blade like the PP Moby. You just may be pleasantly surprised. By the way, there is a glowing review on Revspin.net on this blade.

Of course, like many others have mentioned, to really improve one's game one needs to train and practice hard. The equipment is just a "shortcut" that may help you improve a little.
Good luck, and just enjoy the game!
