I'm a bit curious now what your list of Boeing bombers is comprised of, and what kits you have in mind for each bomber...that would be a very interesting project, and I'd love to see them! Just using Wikipedia I have come across a number not so well known models, preceded by the infamous "X", of course, which appear to never have been put into production...would your list include those models? I love the scale you choose, by the way...same idea behind my using 1/600 for my ship models, where possible...storage considerations!
Cheers!
