Have also tested the optics of a LOT of scopes on a consistently-lit optical chart, while setting all the scopes on the same magnification, and FFIIs did VERY well. In fact they did as well as well-known European brand costing 3-4 times as much.
I also know that many hunters who supposedly "test" scope optics don't bother to set them all on the same magnification--which is essential for a meaningful test--or on a consistent target in consistent light.
There are many other factors involved--but the other thing I also know from long experience with 3-9x40 Fullfield IIs is they hold up better than most other scopes in the same weight-class--including some far more expensive models.
