I like the Thunderchild, I'd love it if it had nacel placement more like the Akira, to me it looks funky to have them over the saucer, and even using the Akira pylons is a limited fix because you loose access to the type 6 material, which is awesome, and because the nacels sit a strange angle.

If Akira went T5 I'd probably use it, but I wouldn't buy the TC variant until there was a satisfactory way to have the nacels in the under Saucer configuration.
