Everyone says they want a tree reticle, but unless a MD makes you do a no-dial stage nobody uses them. Why? If they were really that beneficial, why are we all still dialing elevation? And if we are dialing for elevation, why put up with all of the distraction and clutter below the aiming point?
I use holdovers on every stage with targets at multiple different distances, because it's faster during the stage than dialing for each and every target. It gives me more time to build a stable shooting position and make a clean shot, rather than worrying about time because I have an extra step between each target. I don't have issues spotting my misses, but that likely has something to do with the fact that where I'm at (Colorado) all the misses are just hitting dry dirt and are pretty easy to see anyways.
Different people have different preferences, but I personally like using holdovers. The majority of people do seem to prefer to dial, however.
