For me its the C. Love the Ambassador-Class, sorely underused, and loved Rachel Garrett, she was one tough cookie.
You know he's about to say "My precious." As he fondles the nacelles. I felt the same way with my first TMP refit model.
I've never been a ship pr0n person. But I freaking LOVE the NX-01. The only Trek models I have are the NX01 and the first reboot Enterprise.
I just put them in because they are technically Enterprises, and I kinda like the Odyssey class Enterprise-F design although it doesn't compare to the Galaxy class.
It's such a shame this was killed off in Generations!!! Interesting to see that in the Favourite ship tournament the Refit walloped the D but in this poll it's currently only 1 vote ahead at 13(refit) to 12(D).
Totally agree with you about the Enterprise-F, it's like someone has merged the D, the E & the Oberth.
