That's an excellent choice in sights. I will say, though, the Cobra King Cobra I is better, for a couple of reasons. It's a single pin mover, just like the easy slide.

First, the King Cobra is smoother and easier to adjust. It's also more durable and very well constructed. The pin is brighter, and my favorite feature is that it has a built in quiver mounting bracket that doesn't block the adjustment knob. It's a little more expensive, but only about 10 bucks. You didn't ask, I know, but I would pick the King over the Easy Slide. Just my thoughts...
