I have been experimenting:
Hind sight: Tried it last year. It was decently accurate. It was easy to shoot one pin, but took thought to use other pins. The system is that you always line up the rear sight with the same pin. Then put a different pin on the target. It is counter intuitive and I was concerned I would forget in the heat of the moment. Also, I was never confident with the stability of the rear site. It seemed like a flimsy way to attach it and I was always concerned it would get knocked off position, although it never actually happened to me.
Anchor site. I liked this better. It took a while to set up, but worked well once I did. It does a very good job of getting you into a consistent position and identifying torgue problems. The downside is that it adds another piece of equipment into the sight window. Add the Anchor site and a sight with 5 pins and a bubble level and there is a lot of stuff in the view. I never shot as well as I did with a peep, but it was still acceptable. I also had some concern with its durability as well, but it was more sturdy than the Hind Sight.
Red dot. I am working with a Zeiss Z-Point now and the HHA adjustable mount. I haven't got it completely set up yet. The HHA mount is difficult to set up, so it is taking me a while. This seems to be the best solution for ease of use with both eyes open and for full field of view. It is also very robust, so should be durable. I don't know how accurate it will be. Adjusting for different ranges is going to be slow, so that will clearly be a weakness.
