Currently I have a PVS-14 from TNVC I bought 3 years ago.
L3 unfilmed white phosphor, solid specs.

Now I’m starting the search to upgrade to duals but there’s so many options out there currently for housings, tubes, companies to buy from etc.

TNVC was great to work with previously and my only complaint is the wait time to get it in hand. But even that wasn’t major.

I want to stick with white and want pretty clean tubes without blems. Figured this would be a good place to start and see what people like and dislike with the current products available.

All that said, point me where to research.

PVS-31As are basically the industry standard.  Note that there's no on-board IR light, so you'll need to add one to your helmet.  The 1531 housing is a compromise, and not worth the added weight over the PVS31A, IMO.

My favorite housing, however, is the Theon Sensors housing which is sold as the EOTech BinoNV or Elbit F5032 (PVS-31D).  It has a built-in IR light.  Adjustable gain.  It will auto-shut-off when flipped up, but somehow, not when you just look up.  It will also auto-shut-off pods when they are rotated up and away from your eye.  It's not quite as light as the PVS-31A, but it's still pretty lightweight.  The optics can focus really close (18").  It has a built-in diopter adjustment.  It just has everything you want in a housing.  (Well, except for thermal fusion).

YMMV
