RE: need help with new bow sight
I used the Vital Bow Gear Startrack this year. It's a single pin adjustable sight that has three feet of fiber optic cable and the yardage markers are also fiber optic so you can adjust the pin with a very minimal amount of light. I think they make a light for it also but you would never need it. If it's light enough to make out the shape of the deer, the sight is plenty bright to make a clean ethical shot. Also, its made out of metal so its pretty sturdy. I looked at the Impact Archery sights before I bought this one. They are nice and probably as bright, but I like metal as opposed to plastic anytime I can get it. VBG makes a lot of nice models, you may wanna have a look at them.
