I was able to look it up and Super Heavy booster empty weight is 606000# or 303 tons so I was off on the mass. Since most of the fuel is expended by then it is much lighter then the gross mass of 4051 tons (8,102,000#), but I will concede that at @ 303 tons, that is a decent moment arm to deal with.
