It's only a good racquet for you if you like to play with it. Sorry for mastering the obvious there, but if you could let us know what your current racquet is, along with the general sort of play you enjoy, that might help some of us to give you some better ideas about this racquet's potential "fit" for you.
The 6.1 Classic is among the all-time greats for serve and volley work in my humble opinion. I'm a 4.0 all-court player, but I've also held my own in a few 4.5 doubles settings where I've found this frame to really shine. But it's no exaggeration when our pals here point out that it's both heavy (mine weigh 12.8 oz.) and rather stiff. I'm now 45 and although I've enjoyed those racquets for the better part of two decades, I'm finding that other frames with extra flex like the Volkl C10 also have much to offer me.
As stiff racquets go, the 6.1 Classic is actually somewhat comfortable. Not sure if it's the kevlar component in its layout or the inherent stability that comes with its extra heft. I've certainly sampled lighter racquets with some extra backbone to them that could feel especially harsh on off-center contact. Lower string tensions have helped me to get along with this frame too, but with its extra pop on volleys and serves, I've found better control and comfort around the baseline with the softer racquets.
