I have the trophy ridge matrix and believe it to be one of the best sights on hte market. The sight window is round and it works great with a peep sight. They are avaible with micro pins. Everything on the sight is adjustable without any tools!!!! Was a breeze to sight in. They are very secure there is no fear of accidentally knocking it out of tune. It is a little more than $100 though. They have other models under $100 though. They start at around $50 for the flatliner. They come in either 3 or 5 pin models. The 2003' s have steel pins as well istead of the plastic pins. All in all it is a great sight.
