Spot-Hogg gets my vote. They are a little pricey, but infinetely adjustable. They also make the Hunter Hogg-It now in a 7-pin model so you can shoot to the moon if you so choose. I know they are durable as well. This year, I had hooked a branch when bringing my bow up from the ground, and I ended carrying the limb up with bow because it was hooked to my sight somehow.
