Actually, never. I've only been back to modeling for a few years, so I haven't built that many kits, but I like to do something different every time. I'm definately not a "specialist". Currently on the workbench: 1/72 SR-71 Blackbird, 1/144 Boeing B-314 Clipper, 1/350 Fletcher Class Destroyer, 1/35 Triceratops (dinosaur), and 1/24 Lotus Super Seven.
