Yeah, it is a bit hard to concentrate on but if 'madness likes it, it's going to be good so I'll "Press On Regardless!"
Edit: I just finished the article. It was very good. It is amazing how many changes there were between the S2 and the TC that are very difficult to see. A lot of this information, and more, is available in Matthew Vale's book, Lotus Europa: Colin Chapman's mid-engined masterpiece.
It was well worth the time!
