Hey everyone,
I'm sure the SSTO hype in the community has passed but I'm getting into a bit of an SSTO phase here. I've had success building several SSTO capable of Minmus missions (with mining) and returned to Kerbal. I find this challenge very rewarding and was wondering if there was a lighter alternative to the Nerv rocket. I've done some browsing and can't really seem to find anything as efficient but is lighter and produces more thrust. Of course, it's possible I've been over thinking things and the Nerv rocket is actually quite OP. At any rate -- I'd like to play around with what ever is available. Any suggestions are greatly appreciated.
Cheers!
