I use the OL-5519 on all my compound rigs...they are great sights. I set them to 25y & leave them for hte hunting season. I'm easily on to 35y. No reason to touch the sight or pick the wrong pin in the heat of the battle. Plus, like all mentioned, they are very rugged.
I did have a dial one in the past, but went back to the slider since I like to mark my own yardages anyhow. I also change arrows enugh that I'd be messing with the tapes all the time. So, I just mark the blank white tape with pencil for my yardages.
