I'd caution you check out the TA31's and TA01's with it's terrible eye relief before purchase - have to have eye 1" from scope very dangerous very black. TA11's are superior with 2.5" and larger exit pupil. TA11's are uglier though being so long.
Eye relief is likely not going to be that important to me as I go prone for distance shots, use a spotter, etc.
I am intrigued by the opportunity to use the 3-4x magnification for target ID and reticule ranging while still having good close-in immediate reaction rounds on target capability with red dot. And eye relief with both eyes open is a big factor there for sure.
I like lightweight optics as well as low bulk, which, along with price, has put me off from Trijicon. Maybe unfairly.
As a guy who still relies a lot on iron sights, these optics systems are pretty damn fantastic.
Edit: I went to the Trijicon web site to check out the various models and got a better understanding of their Bindon Aiming Concept (dual eyes on target with magnification.) It doesn't seem like it will take any longer to get used to the magnification than it took with a 1x red dot.
