Well I've been using the Babolat AeroPro for the last year, and recently i've tried both the K Blade 98, and the Head Radical MP. According to most site the difference in qeight is minimal from 11.1-11.3oz all of them while strung. So why do i fell such a huge difference when i've tried the other two racquets, they feel so light. According to my friend he says my racquet is heavy in the frame while the others are heavier in the grip. Need some other point of views. I love everything about the babolat but at least to me it seems a bit too heavy. Any feedback would be appreciated.
