I wonder about raptor re-ignition. They have it down with Merlin but it’s not torch ignited nor full flow. I wonder how well that torch handles being in a lit combustion chamber and what the insides of the preburners are like after shutdown... Ps so so easy to armchair quarterback. I don’t want to sound like I, even one tiny bit, am not constantly dumbfounded by SpaceX’s accomplishments!
