I know about continuous flight auger (CFA), never heard of de-frictionalised piles. I know he gets excited whenever he sees a "Rig" out and about, I just thought that was a construction thing...that and wearing cardigans
He's definitely not playing it cool - its all he's allowed (it is part of a bigger group) without putting in extra dosh. I think he wishes he'd got an e92 now.
