I have trouble focusing on a single pin when using multi-pin sights. Therefor I use an HHA slider, but one thing I found out years ago when I dropped my bow from a treestand. I'll never own another sight with plastic parts. I'll pay the extra money and buy something made of machined aluminum; and that includes the sight guard---especially the sight guard. If you get a good sight to begin with it most likely will be the last one you have to buy. Same can be said for most other accessories.
