I 'need' to choose one of the following scopes for some long range shooting.

Bushnell DMR 3.5-21x50 (first gen)
Bushnell ERS 3.5-21x50
Bushnell LRHS 18x

I have experience with the LRHS and like them but I am keen to try one of the other two if there are benefits. I am not concerned about weight or price.

For the guys that have used them which one would you recommend?

Cheers
