Alas, my ship has proven to be to lag inducing to be of any use, that and the fact that fully loaded it takes 23 minutes to perform a 3000 delta V maneuver and its oscillations during acceleration are worrying and look like under a sustained burn they would rip it to shreds.
All that said, even with the long burns in reality it would be very practical with it's overall high delta V and towing capacity. If you really wanted to you could mount five smaller ships, many probes, and a crew of twelve (Excluding other ships). If you had a powerful computer and the game engine was a bit better this thing could take you ac across the cosmos mining kethane on the way. It's a shame to have to scrap the project but has been a great start and introduction to KSP.
Thanks to everyone who watched my streams building it, it was a pleasure and I hope you will watch my more practical universe with smaller ships.
