I use same button I used for TIR. Rarely need to recenter during game play. Use Voice Attack for a whole lot of commands. If on country I get "WTG", I hit voice button(for recognition in VA) say"Thanks" Types it in Channel, button: say "Salvo 1,2,3,6" it types it in radio and sets salvo as per command. Think I use 26 or so command functions with VA. Including for bomber positions...just have to profile desired "key words" and VA will do the rest. Being that the numbers are diffrent for each bomber, it works better to only use 1 or 2 models in game. If I am ever in an "Other" bomber I just look around my nose, not all that hard to see keyboard, well with Rift at least. The vision and blur you get is just nature of the beast, its a bother but VR almost seems natural and I can put up with it. I use RIFT and havent seen many bugs due to sound/Mic functions. Not sure if Vive has same sort of setting, where you can "Mirror" sound to normal headsets AND Rift headset? The RIFT uses external Sensors, not sure about Vive? I also tried ACER VR but it didnt have attached sound and was a bit clunky, so stuck with Rift. I didnt have "CENTER" issues with it and it was some other system used to track head position, not really sure how to describe it. AH has VR integrated to game play A LOT better than DCS. Sure it can be buggy...but it is relatively new tech...so I look past the the most part of them. As too double vision?? Maybe the spacing of lenses? I havent had this occur in some time, just got used to it maybe?
