After a very successful year with a 2DD reticle, I had it changed out for a CH-3, thinking 'aim small, miss small'. On a bright sunny day, against a light colored target, say an orange target spot on a white sheet of paper... it was awesome. Uncluttered, and very, very precise.
Then reality hit. I shoot in an outdoor sport - F-class, and we don't generally stop for rain or inclement weather (except @ Lodi :

) and if its dark and overcast, ya don't get to say "No thanks". For me, shooting in real-world conditions, I couldn't see that tiny reticle or dot against a black target face worth a dang if it wasn't nice and bright out. The reticle would just fade out of my view - I'd have a nice crystal clear view of the target, just no reticle. I'd have to come out of the scope, relax my eye (try doing that during a record string, and see how easy it is to 'relax'), focus on something else nearby, then get back in the scope. I could see the reticle for about 5-10 seconds, then it'd fade out again. To say that made doping the wind and breaking a good shot difficult would be a fairly major understatement.
To add insult to injury, even on nice bright days, once the target centers start getting a lot of pasters in the middle, giving them kind of a mottled look... that dang center pip (not even enough to really call a 'dot' in good conscience) would just blend right in. I tried everything I could think of, made repeated trips to the eye doctor(s), called the factory to make sure I was adjusting things correctly, etc. Only solution for me was to get the reticle changed *back* to a 2DD.
Not everyone liked the CH3, and not just because its not tacticool. I lost a bunch of points to that blasted reticle, plain and simple.
