The Chevron grip is the preferred grip of Trego. It's fairly basic but is on the bat because this is 'his' bat. For £200, the bats we have hand-picked are very nice in my opinion. I can't speak for PDC but like bats from all brands, there are ones i definitely wouldn't want to go on my shelf, so i don't pick them, they must end up somewhere so maybe you got one that me (or any other retailer who takes the time to visit the factory/warehouse of the brands) decided didn't merit the sticker it carried. All GN handles are very thin so not much can be done there.
I have some theories and reasons to think a GN bat is UK made, but there are no hard and fast rules, and bats i definitely know have been made at Robertsbridge don't always carry these indicators. I am not going to list them here in case things change in the future, but if anyone visits the shop (our forum event this weekend maybe) then i am happy to share my opinion.
