Nice. I like the mesh because they're easier to clean but I think they stay pretty true to the 200 micron size. In my experience, the 200 micron felt filter socks will get loaded with detritus and you'll start to see the actual quoted micron size decrease. Have you ever heard that a filter functions better once there's a little bit of stuff trapped in it? Or remember those old school diatom filters that only functioned once the filter material was loaded with diatom dust? Think something like that. I run felt socks when I'm in town because they get loaded up a lot quicker causing me to change them out much more frequently. But when I'm on the road, I'll run a mesh with the understanding that it will still function without overflowing for a much greater period of time. However, there's still a lot of stuff in the mesh one's so you want to change them out regularly so they don't put off a bunch of nitrates.
