I have a Elite 4200 2.5-10 x 40 on my 30.06 and love it. Man the Rainguard is worth it!
And just got a .204 Ruger and topped it with an Elite 3200 4-12 x 40. Shot at the range for the first time yesterday and I like it very much-can't speak for the bigger models. I do know that my predator friend said he stopped using scopes over 12 power though, because the heat shimmering is so aweful over 12 power when shooting at a prarie dog towns in SD or MT and AZ.
