I have to agree, the Vesta's are smaller in volume but almost as long as the E-E. I do however think that the compact design of the Vesta might be beneficial. True! Aventine was outfitted with more experimental goodies. They might not have implemented the entire landing system from the start for various reasons. Perhaps the system could be installed during the next service window. My only concern would be for the pylons, they need a strong SIF to reinforce them. No problem in normal operations, but I would recommend "saucer" separation in times of emergency.
