For that kind of ISP you need hydralox. Now you've got to accelerate cryogenically cooled hydrogen at 10,000g! Also if it ruptures during spin-up you've probably destroyed your launch mechanism (not that keralox would be much better). At least you wouldn't need much insulation on the tank since it only has to spend ~6-7 minutes in flight.

> that kind of ISP you need hydralox Merlin 1D and Rutherford get close to 350 in vacuum with RP-1. Hydralox would need to be insulated during spin up, which probably makes it prohibitive. In any case, if anything goes wrong in spin-up or deployment, the entire facility is toast. Whether there's a bit of extra chemical energy added to the mix is likely a rounding error.
