If you use the AIS narrow route for a VFR flight and define every turn point in your route before using something like a 10nm wide corridor (+/- 5nm) then unless you are doing a very long route there will not be many NOTAMS.
Yes there are a few unnecessary pieces of info eg why does the Southern MDA have to be NOTAMed throughout the whole FIR?....does a local Lands End Flight need to know about North Sea danger areas?
However, overall if you use the AIS software to it's full extent, it is quite good.
NOTAM plot will not ease your load because it will not plot all the NOTAMS. It will give you a long list of the NOTAMs that it is unable to plot and you have to individually check each unplotted notam just in case it applies to your flight.
The ideal situation would be for NOTAM plot to be able to download a narrow route brief and then plot those thus creating a situation where the unplotted ones are of interest and can be read easily.
