I would like .60 size. If you do it, make sure retracts are an option. I'm still kicking myself for passing up a chance to buy a Cermark F-20 in .60 size. Planes I would be interested in include Saber Jet, Panther, F-4, F-20, F-104, F-15. Others, too, I'm sure. This doesn't mean I would do all of these but probably a couple.
