For stealth? They are kinda large to fit into a hat and not leave obvious lumps.
There are some Schoeps screens (if I recall) which are lower profile, and which might not work as well in high wind, but are less obvious.
If you are sneaking with a stand, the DPA should be fine.
They fit perfectly (if snugly), they are good up to about 15 knots (I am guessing). At 20 knots or more wind speed they are not perfect but they still help a lot.
With any windscreen, a guiding principle is to push it all the way on, then pull it back a ways, like 5-10 mm, so there is a pocket of still air in front of the diaphragm.
The reason I stopped using those DPA screens is that they turn to goo after a long time.
They left a black sticky substance in my mic carrying case after about ten years.
Check the texture from time to time, once they lose their sponginess, and start to get sticky, I'd recommend discarding & replacing them.
I rarely run low profile outdoors, and so I use Movo screens now, though I heard the model I use is discontinued?
