I'm sure this will be the case once I get the base fully upgraded - but I'm finding it coming along slower than I'd like, so I'm looking for ways to save some cash. Oddly enough, the Asparagus Rocket gets my flying fuel can into Orbit for ~ 99K. The equivalent SRB based design does it for 90K. The Asparagus stages cost about 20k a pop, but I could feasibly recover 10k on each ... so effectively the asparagus version would be ~ 60K, significantly cheaper than the SRB based version. But I guess this all is moot once I build a fuel base on Minmus
