Just a friendly FYI, the ULA Delta IV Heavy rocket technically uses asparagus staging, as do the planned SpaceX Falcon Heavy, and Russian Angara 7c. They don't use the ridiculous amount of strapon tanks that you see people use in KSP sometimes, but they use fuel transfer from the outer tanks to keep the core tank full as all of the engine's burn. It gives a significant boost to DeltaV. There are videos on Youtube of the Delva IV Heavy.
