I don't really even understand why we asked for PBS SC bidding in the first place. I never once heard any pilot talking about that during the negotiation process or survey discussions. I guess in theory you'd know far in advance what you're doing, but in reality if you get a rotation on your very first SC that would remove most/all of the SC you had bid for in that LC block. Then you're right back to bidding daily SC since you're still going to be given your max anyways.
