Go for the Falcon, but the Menace is a better scope, feels better built than the Viper and I have seen 2 of these develop faulty paralax adjustment.
The Bushnell 6500 2.5-16x42 is by far the best scope, smaller and lighter and zoom for target work, but you pay for the benifit.
Make every shot count
