Using the closest engine to core would tend to push tail into core engines... want the opposite effect. Use the center engine and when the nose is rotating away from center core at good rate, use TVC to kick tail away from center core. You'd be neutralizing some of the rotation, but physically pushing the tail away from contact.

What is the ice from inside the nozzles?
The consensus seems to be that it might be TEA/TEB residue from previous firings.
Can I just say how beautiful FH is?Looks like titanium grid fins on the side boosters but aluminium on the central core.
Interesting that the two side boosters seem to be different ways up ...--- Tony
The two side cores are identical, ie the attachment points are at the same point on the radius of the octaweb - hence when attached to the centre core, they will be "different ways up".
