I watched the Majek match now and here are some comments: Fed's BH is looking much more confident now. His balls are not landing short. On a very high backhand, he still managed to raise his racket and drop the ball in reasonably. The accuracy on his FH has not been compromised as feared by many His serve is not the same as in his younger days, but I don't see any further loss in precision due to the frame. In fact, they are bouncing higher I feel. His drop shots are sometimes going a little further than they should, but that should resolve itself with time. Though I cannot prove this, I bet he is also expending less energy overall with the new frame as it gives him free power.
