I have no collection so no logic but seriously I'm thinking about getting only Japanese bikes but only one in each type (touring, road...). I already have Koga Miyata touring bike and Kuwahara CX. Don't know if giving up Italian bikes is a good idea tho.

Dedacciai and Miyata have their own steel tubesets. My track bike is build with deda.
