So having two blurred sights doesn't bother you? Have you put thought or practice into why you prefer one over the other? It's the same parallax issue regardless...
And when you talk about focusing on the sights and not being able to find the target, are you switching your focus (first focus on and find the target, then bringing your focus back to the irons), or "riding" the irons as you move/transition?
The second blurred sight, for me, with a hard target focus, is far off to the right and I can clearly distinguish the one in front of me to line them up properly. So no, I don't have a problem with two sights.
I haven't tried a hard sight focus in a while, but doing some stuff dry in my house if I do a target ID then back to the sights I feel I am wasting a lot of time switching focus. My focus doesn't transition very quickly. Maybe it's because I'm so used to my target focus, or maybe my eyes are just a little funky. I know a lot of people see these things a lot of different ways depending on their eyes.
