Update: my "path less traveled" BB ended up being BB9 - lucked into my GW1 4.5 fwd having good xmins for a good fix, combined with a ~good fixture for both my GKs. EV on bench was ~13, didn't impact my transfers before or after, scored 14. Overall, happy with taking the opportunistic BB approach.
It seems BB1 will be popular. Given the EV differences between any and all chip strategies in the first half look like they will be quite low, but there are (fairly remote) upside cases for later chip strategies, I think I will prefer to choose outcome polarization and take a path less traveled (🌍)
