I've only got 2 bikes at the moment, a Sandy Gilchrist custom built and a '63 Flying Scot Continental.
Much as I love the Flying Scot, I couldn't bear for it to be chained up in the office garage all day so I use the SG for commuting. As the SG fits me so well it's always my bike of choice and I must admit to nearly having palpitations when it was damaged coming back from Amsterdam on the plane (Luckily only the back wheel)
I understand how nebill feels. When I got rid of my old gas pipe special for the SG, even though it was a heap, I still felt sad. All those miles covered, memories of great cycles, memories of bad cycles(but never that bad), all the tinkering and upgrading and adjusting.
Must stop, it's getting hard to type with tears in my eyes
