I have some Super slams and older grand slams ......both have been just fine. I'm starting to see the newer grand slams at better prices. Just wondering if anyone has used one in the field. IMO the super slam offers excellent performance and the older grand slams have been solid performers. I think both are light optic works products which is known for quality.you can pick up 3-12-42 for 250.00 which seems like a good deal.
