More comfort typically comes with a softer stringbed and/or more flex in the racquet. Extra flex can take away some of the pop that you may be used to and more weight in the frame can compenstate for that - the added heft brings extra inertia to the collision with the ball and a heavier racquet can also feel more stable. At least for me, stable is comfortable.
That n1 is a very light, very stiff (lots of zip), and also head heavy racquet. I'd expect that you could find some comfort in a softer frame, but you need power, too so that means something that's heavier. If you want to be able to handle it okay, you'll want it to be head light in balance. The Babolat that you mentionned is an 11 oz. racquet, but you might be fine with something even as heavy as 12 oz. as long as it's rather head light. If you demo some gear, don't be afraid to try one or two frames that are more hefty than the Babolat that you've used - if they're too heavy for you to reasonably play with, you'll know it before long.
In case you haven't tried different types of string in your Babolat, I'd recommend that you sample some livelier string before you invest in a different racquet. Tecnifibre Biphase has a good reputation for comfort and power, but there are several good multifibers around. I'm partial to LaserFibre's Phenom XRC and Pro Stock, but there are several good ones out there.
