Mmm. And the Archer was outright a noncombatant, and the Newton wasn't exactly great as an answer to D6s, nevermind D7s.For reference here are the shield stats for the Newton and Archer which were on the older shields (probably used Standard sized shields).
Assuming we're going to aim for the lower end on mass, I think that settles me on the Standard Covariant; we can make a better combatant than the Newton while still being a more than adequate biological science vessel, and I think we should.
