I've got about 15 pics of this area alone, from several angles, and have rivet detail of the entire skin, top to bottom, front to rear. It is different in places from variant to variant, depending on whether it is the "standard" or "heavyweight" airframe. The narrowed rear window is one of the details I immediately addressed when I started building, as it is probably the most glaring departure from the true scale lines.

It may not have shown in any of my pics, but I did lighten the ribs prior to skinning the wings, by the method you describe. I still build for crashworthiness, as my building skills remain better than my flying ones, and I hate repairs, and want to keep my 'Dawg flying as long as possible. There's always the accumulation of hangar rash and transport dings, and edges seem to be what takes the greatest amount of hits. Traditional methods are what I know best, so I'll stick with them for the most part, they've worked well for a long time.
