The question is, which HLLV will we have? If shrouds are to be lightweight, foam strikes will still be a problem. I'm thinking that if we do get an in-liner, it might be Magnum/Longfellow sized. I'd like for the HLLV to be as big as possible for larger payload volume, reduced assembly, etc. Damphousse seems to be pushing for SPSS, as Coyote Smiths heir as it were, and right now, if SPSS is what gets an HLLV built, so be it. Then Kim Reh and others who want Kuiper belt landers, Europa cryobots, and the like will have a ride for automated probes beyond the limit of what is being offered now.
