If it's that light line on the side that's just the core, it's not cracked.
Really? Oh, than I'm back to being happy with my new board
After inspecting the entire board, I found like three more of those, but they were much less visible. So, anyway, what makes the core look like that? I'm probably VERY wrong about things, but the one in my Lamar looked more solid [as in, without any crevices and stuff, not more durable
]. And by the way, thanks for lighting fast replies!
