I guess by relatively light I meant that I would like the bike, put together with wheels and full component set, to weight about 20lbs or less. However I guess that would largely depend on the wheels and components. I just didn't want to purchase frame material that would give me a tank for a frame. I do agree with your suggestion to start off with thicker butts, I do believe I will do that. I was considering just going with Nova or Dedacciai tube sets on the first go around to get some practice in and to learn off of. Did you guys use lugs or fillet brazing your first build? Oh and I appreciate the help!
