Nice work. It is indeed a long and winding road, one that goes ever on...(to quote some people!). However, if the course is stayed, the end result is always worth it.
(Ive never used the visors, I use an angle poise lamp with a magnifier lens built in and a daylight bulb behind it. I still sometimes get a little cramp and tired but generally its very good. Keep it up and if it helps, its a winner).
