I haven´t played with it yet, but I do not agree with those saying that it feels "heavier than it should". My feeling is that its weight is just the weight of a 140 gr racket. I have a feather 135 and can´t tell the difference. So, no, I would not say that weight is an issue.
as soon as I play and use it I will come back to tell about it.
Right, now that I have played with it I can tell it feels really good. Power is there, and I have noticed this specially on my backhand. it is true that compared with my feather 135 it feels heavier WHEN PLAYING, but....it is a heavier racket (140 unstrung) so that is as expected.
the only issue for me is that the grip (handle) is a bit thin, but putting another grip on top of the original one solves the problem for players with big hands! not big deal!
So far....so good!
