I'd go for the Burris FFII. I'm not sure about Lawnboys pentax. All I know is that I once looked through one of his scopes that was on his 30-06. The scope looked like it was from the eighteen hundreds. I barely made out a tree at 50 yards in full daylight...kind of looked like the tree was surrounded by a blurry cloud. I thought that has got to be the worst glass I've ever looked through. Then a week later he calls me and says he dropped a six-by bull and in his story he say "I could barely make it out." Long story short any scope would be an upgrade and a pentax recommendation might be scewed.
