There are only certain bikes I would keep orig spect, high end that work well already, bikes with a historical identity or are so original that I would feel bad about altering their status.

Saying this, I only ride bikes that fit me well and are comfortable to ride. I started out with the mantra " must be original spec " but really got tired of the long project time, lack of riding time with it, huge cost, and the overall feeling of discomfort with the bike when I did finish it.

IMO, find your own way...
