haha, thx for the kind into asl !
Yes, I've been using thermal & NV on head now for 7 years. Q-14, IR-Patrol, various COTIs, Skeet, Breach all with or without 1 or 2 PVS-14s. But as always, it depends a bit on what you are trying to do.
The cotis are great for enhancing ability so see/hit critters in vegetation with laser. There are cases where the thermal can see the critter, but the 14s can't, though the 14 can still see the laser. This sort of case is the "magic" of fusion or the thermal overlay. Here's my latest coti type setup.
CP Nightcap with 14 and C5E on left eye. Right eye open. This is light and unbulky and the 640 on the C5E gives enhanced PID distance over the 320 COTIs that only have 20 FOV. However the 40 FOV on the C5E does tend to completely obscure the NV view of the terrain. You can turn down the thermal, but that doesn't improve the thermal's ability to PID the critters. The NV can of course see the laser or other active light source, regardless.

Here's two 14s with a 320 coti, another standard setup. This gives you some depth of field with the dual 14s and still the ability to detect critters and even PID/shoot with laser close in. I use this sort of setup mostly in the warm half of the year as the vegetation closes off lines of fire thru various tree lines, which in the cooler half, I can shoot thru with bolt guns off tripods.

Now here's just a breach and a 14. The breach shines for navigating thru the woods on "dark" night (no moon + overcast) ... the 14 as always, can at least see the laser.
Comparing the breach to the coti 320s ... the breach can detect farther out, the coti can see a bit more detail closer in. About 600yds detection range for the breach, 500yds for the coti 320s.

Here's a varied line up, from left to right:
single 14
single breach
14+Skeet
14+Patrol w/ 3x magnifier

Here's a skeet with 14 and coti on one helmet setup.
This gives the best of both worlds. Long distance detection and PID with skeet, short distance fusion/thermal overlay for shooting with laser with the COTI and as always, the 14 for seeing the laser. T

So, again, whether to use a thermal monocular or a COTI on your head, for me, depends on what distances I am expecting to be observing and/or shooting. For closer in fast shots with laser, definitely the COTI, for farther out observing/PIDing, definitely a monocular. Or if doing both, then both !!
