I love building up a frame my way. I enjoy doing it and I find that it is less stressful to have a personalized built up bike since you can do whatever you want with it without worrying about correctness (like adding headlights, bags or other accessories).

But on the otherhand, I have a great appreciation for original/correct vintage bikes and whenever one comes to my possession I have a hard time not keeping it original. So I usually sell it so as to keep it safe.
