I see glimpses of what I'm after, but I'm not there yet. I know I like race bikes. There are some design elements I know I like, others I'll never do again. I just keep tweaking areas and trying new things. Initially I wasn't attracted to socket drop-outs. After I did a few sets I saw they have some unique advantages and I have now taken a liking to them. I've found sometimes I know what I don't like after I've tried it. I've over used ornamental holes, cut lugs I don't like, used way more stainless than I like, etc. I guess you have to try it all first, then decide on it's merits. And when everything is new it's easy to get overwhelmed and blinded. I think I'm heading in a minimalist direction. Small details, smaller lugs, very little stainless, classic lines, unique paint. Most of all I want to get the pieces in the right spots so it looks and rides like a race bike. Sometimes I feel like I'm circling it with a slow spiral. Frank Lloyd Wright did a good job.
Thanks for asking, I hope this helps. I know you've thought a lot about it.
