I have to say that in general, I'm not a big fan of custom stocks. They often strike me as overwrought, with lots of unnecessary swoops and bells and whistles and easily-dinged sharp edges.
But THAT one is gorgeous! Elegant styling complementing the action, functional details, lovely wood, well-integrated adjustable butt. Just plain beautiful!
Gorgeous and a thumbhole I have an R9 I'd love to put a way prettier stock on, just torn between one of the CS stocks or another laminate like the one I got for my HW95.
