am thinking about upgrading my night vision capability... can anyone furnish any first hand anecdotal comments... anything from Sionyx Aurora to AN/PVS14 white phosphor?

I have a couple of pretty good light gathering gun sights (4x32 ACOG)with 8mm exit pupil on my most likely used rifles as well as some pretty good weapon mounted lights, but would like to be a little more covert... regards..
