LOL Well after hunting and shooting with them for the last several years on many different guns ranging from 243 to 7mag to 30-06 and others as well a a 4x32 Prostaff on a 50 cal inline mz I have yet to see a poi change. As far as clarity of glass...the Monarch is much better than the vx-iii I have, In fact the Pro Staff and vx-iii would be pretty close. Pricewise they arent even comparable. That may not be your opinion or experience but it is mine.
