What a collection...10 Phantoms! I am jealous! I guess it would depend on your display area and budget. Like for me, I'm just using old bookcases so I don't have a lot of room for big displays. Therefore, I just display each one model individually. I think that circle display could be really slick, but that would be a lot of space to display, not to mention a lot of dead space from the edge of the circle to the corners of the display case (assuming you have a big display case, that is). If you can't do the circle-display justice, then I'd stick with the tarmac (check this link for ideas of how to make tarmac sections). I personally really like the look of active displays, and putting the Phantoms in their element could add a lot of life to them all. Ooh especially if you can add some ground crews, pilot/navigator figures getting into or out of their fighters, discussing their flights, etc. I know a lot of people like "what-if" models, but I think it's cooler to have "what-if" displays, like where a 1958 Air Force testpilot would be chatting with Duke Cunningham and Willy Driscoll in 1972 next to their respective birds. Then again, maybe I'm the only one who gets a kick out of that stuff...good luck with it all and be sure to post pictures of the results!
