I have to disagree, pendulum sights for the most part are outdated, and don't give you as good of options as either a slider or a multi-pin fixed sight.

As to what IS the best sight, there are so many, and it's all personal preference. The Extreme RT1000 looks pretty nice, though it doesn't appear to have a LOT of fiber. I really like my COBRA Sidewinders, personally, and SPOT HOGG makes a lot of guys list, but who wants to spend that much money on a sight, then spend some more on after market fiber??? I think it depends on what your ultimate intentions are. That G5 sight looks pretty nice, I think picking a sight is kind of like picking a bow though, I don't believe I could tell you what sight is best for you it's more a personal decision, that entails looking at all of them you can to make the best informed decision. Good Luck!!!
