He was using VT Elite. That (in the picture) must be X90, doesn't make sense switching to the original head light and flexi Kinesis.
I had the X80/90 in my hands, they have a gloss finish instead of the matte colour of the kinesis, it's a sort of purple/blue/black blend that seems to change colour in different lighting. So despite logic, it seems he did switch from a heavy/headheavy racket to a light ultraflex racket.
It would be great to get some reports on these maybe some reviews now that they are on sale in UK. Specs aren't very clear. Difference in stiffness in particular...
I am aware of two cases of broken kinesis (the original head light). Almost new rackets, broken at the top of the frame on the twist point - no mishits reported. It would be great to channel further information here so we get a better image. I tried the original kinesis and I was very impressed - very powerfull and fast in the same time. X90 could well be a beast.
I've just recieved my Carlton Kinesis X70, will give it a swing tomorrow. I've had a professional restring to BG80 at 22LBS (regular tension here in my area, that's around 10KG). The added spec. sheet, that was on the stringbed lists the following:
Carlton Kinesis X90: Head Heavy, 86G in weight, Extra Stiff
Carlton Kinesis X80: Head Heavy, 87G in weight, Stiff
Carlton Kinesis X70: Head Heavy, 84G in weight, Medium
All three rackets are 675MM long. I can take pictures later as well, the racket finish looks very good!
P.S. Edit: I've played with the Vapour Trail Tour up to now as well.
