I have been wrestling with price, clarity, eye relief, FOV, short bush cutline, and long range to about 500 to 600yds. I keep landing on the Burris six x 2-12 for a 300wsm. The field of view is stated at 50ft @ 100 yds which is very respectable, and it appears to have good light transmision, at dusk. It isn't a Swaro, but seems pretty darn good. I have been doing a lot of opinion reading and haven't heard a lot of bad about the Burris toughness either.
