Your Componon-S is an excellent lens. The APO-Componon is noticeably better, but for 11X14s it is probably not worth the $. As I understand it, the G-Claron is of somewhat lesser quality than the Rodagon-G but is often favored for portrait printing. The Rodagon-G is excellent, but I have no experience with the G-Claron. If you can find them, the 150mm EL-Nikkor and APO-EL-Nikkor are both outstanding. For what you are doing, I would stick with the Componon-S, unless I had an urge to spend excess cash.
