I've been carrying around my first frame for the last 30 years. There were a couple of problems with it that I didn't have the equipment to fix. I recently decided that was silly, so I'm making it ridable. I'm a little worried about it, but I'm just riding it around town and I'm making a new fork so hopefully if it breaks it isn't going to hurt me. The thing is, when you build your first you don't really know what you don't know. If you build with lugs, there is almost no way to know what it's like inside. So a first frame with fillet braze has advantages in that sense.
