I have been using the HHA Optimizer Lite and I really like it. I'ts built like a tank. I have dropped my bow THREE times (ugh!) while trying to get used to not wearing a wrist sling and it never lost it's zero. It is the brightest single pin sight I could find. I also have a light for it but the pin does not get any brighter in the daytime with the light on. I can not say that about my last 2 sights.
