I'd use it! Why not?! What we have currently obviously isn't working. Tunnel vision/adrenaline/complacency are probably the cause of most accidental shootings so anything that helps push through that is a good thing in my opinion.
I drive a car with electronic handbrake, ABS, stability control, fuel injection. I wear a seatbelt and have full insurance because I know that I'm not immune from making mistakes.
