I liked the Aerojet LR-87 better because it was designed to be mass produced, was very simplistic, could take several different types of fuel, and had a better thrust to weight ratio.

Great test PWR but why can't we just use RL-10 for the SLS upper stage? This wouldn't be a porky pig project would it? ;)

Many congratulations ! At least a few rocket folks seem to be able to do something.
