Question to users or people with experience with the Nexus and and the Athlon Cronus G2. How does the glass compare and is it a forgiving type of glass for older eyes. Also turrets and tracking which one is better and how. I do alot of shooting out to 300 yds with my FX Impact MKII in 25 cal... I have a Athlon Eres ETR. Scope works great tracking great but I would like better glass for higher definition and clearity as well. What are the thoughts between the two others scope that may offer something better.
