BTW, to get back to the OP topic, I've updated and finished my essay on the Oberth class. I had to shorten it, as I was originally speculating about possible new designs to replace the ship in TNG-R, until the knowledge that that won't be happening. Oh, well.
Sometime in the near future I'm going to write up another essay like this, focusing on the uses of the Reliant studio model in TNG (and its one use in DS9 as the Saratoga). And hopefully I will be updating my woefully behind conjectural classes essay too.
