I have the big brother the HDMR 3.5-21x50 h58 and it is a fantastic scope. I really want to try the LRHS 4.5-18 it looks like a great scope as well. I have been overly impressed with the glass quality of the top end Bushnell scopes. My HDMR has a clearer brighter image than my NXS 5-22x56. The LRHS does have a 30mm instead of 34mm main tube I don't know how much that would affect light transmission and therefore image brightness. But the HDMR is a very big heavy scope and the 30mm tube might be an acceptable trade off to get a smaller lighter hunting scope.
