For our fed campaigns, the connie is definitely the most common. Especially these days with us old folks riding the nostalgia feeling of the original trek. In younger days we did the baker, chandley, ranger, galaxy (when tng first came out), and a homebrew transwarp scout ala nelson. We were much more into experimenting then. Other than fed campaigns we did d7s, l9s, l24, k23, and I faintly recall a gallant wing.
