If you haven't used a holographic sight wingshooting, I dare say you don't know what you are talking about. I have used one for various clay games and waterfowl with great success. The only reason I quit was it was a Weaver Qwik-Point and the mount was forever problematic, and it was bulky, and it restriced the field of vision, and it was heavy. But, when everything was right, I could shoot anything better. International skeet or trap and sporting clays included.
With a holographic sight you don't have to take your eyes off the target; the target and the dot are in the same focal plane. i.e., they both are in perfect focus at the same time. All you have to do is establish the flight path and desired lead and you hit the target. You do not need cheek weld or any of that. I do think good form helps, but as long as you can see the target and the dot you have all the info your brain needs to make the shot, assuming you know the lead you need. You do not have to "aim" any more than you do with a rib and a bead, but it is far more precise with no additional effort. And you don't put the bead "on the target" and hit anything flying either. I even did some occluded sight shooting, where I blocked the tube and one eye saw the target and the other eye saw the dot and I managed a 23 at skeet that way.
I have been very tempted to get a SpeedBead, but I have heard negative things about the mounts from a couple of people I trust.
If you haven't tried it, don't knock it. If you tried it and didn't like it or do well, please share your thoughts on why that was too, please.
