No details on the 2016 Kook range yet, but we are seeing it early next month.
As for satisfaction with Kook bats, i would ask where you guys purchased your bats? I know
@ProCricketer1982 went the warehouse and picked them himself as he was a sponsored player at the time, but as that isn't possible for most people, I would suggest relying on retailers who handpick, and there aren't that many UK retailers who handpick their bats on a regular basis, most of them are on this forum.
We are very close to Kookaburra and visit all the time, averages out to at least once a month and I'm always happy to take requests if someone is looking for something in particular.
