I use mods sparingly.
Mods can be the source of bugs when DCS changes version, mods have to be updated separately. A lot of bugs end up being traced back to mods.
When you have problems, the first advice is going to be to remove all mods and re-test.
That is reasonable, as DCS API and behaviors the mods depend on can change at any time and break something and it is not ED's problem to test with every mod. And some mods may no longer have active dev support.
Mainstream mods like the Blackhawk and A-4 would probably not be a problem often.
