I think if someone is looking for a radical difference between steel bikes, they are likely to be disappointed. My current frame (oversize Spirit for lugs) and previous frame (early 80's Italian Columbus SL) couldn't be more different, but I don't think I could tell the difference other than the steering geometry. Maybe if I was a little stronger, there would be more difference. My criteria for a good frame is that you don't have your attention called to it while riding.
