I did use shoot back in the days, was great, used it for comms only, for maximum realism/immersion. That was a few years ago, don't even know if it's WinVista/Win7 compatible though, I stopped using after I updated my rig. The thing with this software is you have to "train" it so it gets used to your voice. The more you train it the more effective it becomes, but it took away too much fly time :D
