I don't use the Matrix or the Rhino. I've been using the Mantis V-drive and like it a lot. The only thing I would change is the pin size. I'd rather have a .019 pin than the standard .029. Other than that it is a solid performer.

I've had a Matrix, and it is a good sight too. I like the looks of the Rhino and have considered giving it a try, but didn't feel like changing from the Mantis.

I'm excited to see what the Outfitter X sights are like when they come out. They look like a good combination of the Matrix and Rhino with easy to replace pins.
