Helmetfire,
What type of moving map do you have fitted, and as CASA are pretty narky on such things, is it approved for IFR Nav. We have a moving map system (an extremely accurate Avalex one that can even tell us who owns the plots of land, their daughters age, how may beers in the fridge etc - well not the last one) but stamped in large letters NOT TO BE USED FOR NAVIGATION it is not of the right level (B I think). For crab, yes we have maps of the paper kind as well but would have to dust them off to use them. All amended and legal but they are 1:1 000 000 so not real good to navigate at low level on.
As I operate in WA, the comparison with sandpaper is very apt - we have the worlds best beaches here - about 1000km wide all the way around. That said, normally pretty easy to guesstimate 5000m vis as there is always something around.
With regards to the FLIR being fitted, we have a FLIR Star Sapphire III and find it works very well on its own or in conjunction with our NVG.
Cheers.
