Here's a report from zerohandy...
Report:
I have U4 (23") w/stock shaft(Maybe NS PRO UT). I played it yesterday and used 2 times. First was tee shot. I hit it lightly intended to hit off the ball around 200 yrd, but failed... I hit it 240yrd... he..he...Secondary, at the 18th hole (par 5, 564yard) i hit off the ball over 300 yard with my X-Drive 405. The remaining is only 260. I tried spoon but did fatshot. I rolled only 40yard and the ball sit in the deep rough.
I picked up X-UT and hit the ball verrrrry clearly. My X-01 ball fly and sit beside the pin within 5m. The trajectroy made by X-UT was not so high. It was a little bit of fade.
I'm falling in love with my baby..X-UT.
It will sit for a long time in my bag.
