I know Tom was a big fan of a methane Merlin. Obviously you’re trying to eek as much performance out of the propellant as physically possible but did you ever second guess if you should have just done a methane Merlin as a starting point?

He became a big fan of methane, but was not pushing it initially. That came from me reading about Soviet methane engine tests that got over 380 Isp. At that Isp, a subcooled methane stage gets slightly better delta-V than a hydrogen stage.
