I currently have the Viper and like the scope a lot. I am shootin in F Class comps on occassion and feel like I need a little more to be able to dial it in well at 1000yds. Will I notice a big or worthwhile difference in the upgrade? The Sightron is $950 so I would love some opinions before I spend that much. This would be by far the most expensive scope I have ever purchased and just want to make sure its worth it. I really want a NF but cant justify that at this point. Thanks for any input or even any other recommendations at $950 or less (preferably). Thanks
