I'm working my way through Chimonas' book on lugged frames. Not only will this be my first time building a frame, it will be my first time doing any major build on a bike. With that said, I was pretty intent on putting track ends on the bike until Chimonas highly recommended vertical drop outs.

Before I go ahead and disregard Chimonas on my first bike, can someone explain a little further why putting track ends would be a disaster? I should mention that I'm building this without a true jig. Maybe that has to do with it.
