Ahhh that is right, I had forgot about that. Usually what ya wind up doing is cranking the tilt of the mono way nose down in order to get the eyepiece close enough to your eye. Then ya walk around with your chin lifted working on a nice case of neck strain. Norotos has plates with extra holes drilled in them for moving the mount up but your are still stuck with the folded height problem.
The PT alpha helmet padding is thick Thick THICK placing the whole affair far away from your eye. I am not a big fan of the PT alpha. The Ops Core bump Helmet is a GRAND idea but, like you said wallet busting. Heck you could probably do a MICH helmet cheaper.
The Wilcox height adjustment lever when locked down is VERY Solidly locked down, I mean it is very hard to get undone. Once it is undone though the up and down movement is completely loose. The screw knob on the INVG is cool though as it acts as a micro adjustment to get the height EXACTLY where you want it.
The break away feature is a "nice to have" IMHO, and unless you are going to possible getting in and out of vehicles or running through doorways with your NVD on your head the benefit is negligible. I have always been afraid that if I ever smacked the 14 hard enough to pop the break away feature, the 14 was going to be done. Granted a neck injury is a worse thing but I don't feel this outweighs the features of the INVG.
On the Helmet selection, Consider finding a different helmet. I have used the Bell faction with great success and I am in the middle of modifying a Protec helmet at the moment. I picked up said Protec skate board helmet CHEAP on overstock.com and I am retrofitting it with helmet pads an Ops core VAS shroud and suspension system.
Now all that being said have you considered either of the face mask options? Norotos makes a nice one as does L3 / Litton.
In closing I think if your purely going to be mounting a PVS 14 and not dual tube goggles, the stow feature of the INVG is the shining star here. All the other features are great as well but the stow takes the cake. Also a few posts up I said that the Dual Dovetail Adapter (DDA) does not give you side to side movement, that is true BUT.... I just talked to Norotos this morning and they have changed the DDA to where it now adjusts side to side. I ordered one today and I will report back next week on how well it works.
