I have a Tru-Glo Brite-Site and think its a great sight. It is a single pin adjustable sight, and has a full meter of FO material wrapped around it to collect light. Very bright even past legal shooting hours. It has a level also. I checked out the Impact Archery line, and Vital Bow Gear sights among others, but decided to go with the Tru-Glo. I'm happy with my decision.
