Well, I'm a fan of larger reticules with sharp edges. My viewpoint, from my own shooting, learning, reading, contemplating, mediating, masterbating, eating, sleeping, working, etc...
Is that the TA11D felt awesome when I owned one. I've since used the donut and chevron, and I still like the triangle best.
When I get all hyped up and go for fast target acquisition, I like the big bright BAC of the triangle. I was on target every time, and like EagleCP pointed out, I too was double dribbling my eye socket off the ACOG.
Plus, I never shoot beyond 200 yards with my AR. Not in Maine. So short to medium ranges with some CQB makes the TA11D a great choice...
for me.
Again, I'd like to point out that I've since sold my TA11D, and now I'm looking to get another one.
ACOG's are like women you meet in bars, some are easy on the eyes and sweet to use, others don't look right or feel right and would just assume give you a black eye.
