I am glad I stumbled upon this thread. I have a pair of Titans and was looking to upgrade my monitor. I have been doing a ton of research and have slowly come to the conclusion that while awesome, there are many headaches. While I do enjoy tinkering, when I just want to play a new game, it would bother me that I need to spend time just figuring out how to make it look right on the monitors. After many YouTube videos and 15 page reviews, I am coming around to this 21:9 aspect ratio (2560x1080). I am glad to hear that it is going good for you as Arma3 and DCS are also the main games I play. Have you tried any other games? I have read that some games still need some edits to get the FOV to match up to 21:9, has this been a problem for you yet?
Also, I am really interested to see how you built that PVC rig for the cockpit. I just can't justify a $1,000 cockpit for one or two games, even if I play the shit out of them.
Can you guys with the 21:9 monitors elaborate on why you decided on the model you purchased?
