There are some that hit great with it, but it still looks awkward to me. The swing looks too contrived... I don't fancy having a bent elbow at contact.
Try getting the feel of having your arm thrown forward and around as you hit thru the ball... If you look closely how Nadal hits his FH, his arm barely dictate the movement and direction of the swing. His arm looks as though it's limp as it's flung around his body.
