Ive got a pro issue kook, Whilst im impressed with everything about the bat, Its on a par with my £145 itias bat in its prime.
The only difference is the ping. The middle on the recoil is pheonominal, wheras the middle on the itias was good i still had to put alot of effort behind it.
I really think its luck of the draw with willow and performance. Ok pro issue bats may be more asthetically pleasing but is there really any evidence to prove they perform better.
The pro bat i have, for some reason has certainly given my a psychological boost, which has improved the quality of my game due to the confidence boost
