None of the above . And here is why.
Go with a Rhino 2 with Dovetail and a Mod Armory Light Weight Bridge.
Night Vision Helmet Mount Dual PVS-14 Light Weight Mounting System offers an adaptable system to be configured for dual tube technology.

Strongest, most versatile setup for a one and done most cost effective investment.
1. It allows the most compact stowing of a PVS 14 single, PVS 14 Duals and/or either of those with a Pas 29 COTI attached as well, much better than any other mounting system.
2. If you want to run a very slimmed down single you can take the mounting arm off whatever side you choose via taking out the shoulder bolt and removing the arm, or just leave it on rolled up. Whatever suits your fancy.
3. All of the Noisefighter arms (plastic) that attach to a PVS 14 are too thick to allow the proper installation and orientation of a Pas 29 COTI. That is an absolute deal killer for me. The Mod Armory arms are strong thinner aluminum which allows for proper installation and orientation of the Pas 29 COTI.
4. You can also mount a Breach or other HMT onto the Mod Armory Bridges via a multitude of adapters they offer.
5. To me, passive aiming over IR Pointer/Illuminator is much overhyped for taking real world shots due to such a typically poor sight picture that does not allow enough PID when trying to sight NODS through any day sight especially in low light conditions. That being said, the ability to switch a single PVS 14 from dominant shooting eye to non dominant non shooting eye is moot. Thermal is the best passive shooting solution once PID has occurred
6. A force to overcome beats a pushbutton in a amped up situation.
7. A mediocre NV tube with a Pas 29 COTI will smoke even the highest rated NV tube by itself on detecting live critters out there, all night, every night. So any mount I would consider has to be able to offer that ability to correctly configure a Pas 29 COTI and not some half ass, I got it stuck on there method.
Anyway, that is my quick and dirty on the subject. Can probably think up even more good reasons if I put my mind to it.
