So your about 240ish FPS? I have always used single pin sights. I just dont like the clusters of multiple pins. I suggest you look at the HHa sights they are second to none in the single pin industry. The are sweet. I have the new dial type versus the slider that I use to have and I want to tell you the dial is nice. http://www.hhasports.com/Sights/OLiteElite.htm
