I really like my Trophy Ridge v3 sight, mainly for the verticle pins, but also for the extra length dovetail and thumb screw adjustments. The view through this sight is unobstructed. I use mine with a rifle sight instead of a peep sight, so the long dovetail is a must. Here is a video of it on my bow. The video is regarding something else, but it shows a clear picture of it mounted on my bow at maximum extension.
