Reaper,with your skills and training I would guess you would see a big differance using both tools,I love the PVS-14 with the IR for target ID and the shot,I mount it on the back of my day scope,In your hand or rhino mounted it can be good for spotting,but I have found that when the grass looks white or yellow in the standard night vision,it can be hard to see lighter colored coyotes...The FLIR on the other hand is almost cheating,there is no way for them to beat the heat signature..
Also I find that the WHITE HOT,BLACK HOT,and RED HOT features
can make a big difference given terrain,wood line and seasonal variations.. For Example in summer given the ambient heat given off by all the trees and rocks I use WHITE HOT or RED HOT for viewing so I can make out if I have a live animal down range,in winter in large fields with snow I use the BLACK HOT feature..
If the nightvision and thermal are legal in your state give it a try..
