There are lots of varieties of FO sights. You will want to look at a few to determine what width and height you want for your blade as well as the width of fiber you want to go with. Some like a small dot, some want a glowing basketball. Fiber gets less vibrant over time as it gets exposed to oil, dirt, etc. so you'll want one that the fiber is easily replaceable. I like to change colors periodically as well because I have a bad habit of looking over the top of the sights and I find that the color change tends to draw my eyes back to the front sight where they should be. Agreed that Dawson sights are quality and they offer a wide variety of choices.
