I remember [MENTION=46029]fender1[/MENTION] observed that with all of his horse trading and building and rebuilding, he kept ending up with a bike of the same design. I've used that as a warning to myself. I do have some overlap, but my bikes are moderately distinctive from each other.
If your bikes tend to be too similar, I think the quickest way to make them different is to change the handlebars.
