1 guy had a PVS-7. K also said something to the extent that if you can afford it go for it, but 2 PVS-14's with the T swivel bracket is best cause you have more options and can always lend 1 to a buddy if need. I have heard others say that if you have NVD's on both eyes that if a flash goes off it momentarily takes out both eyes. K refuted this argument pointing out the gated/gating features will protect your vision in those circumstances.
