Valve cover breathers

Read too many threads about oil mist getting all over to use breathers.
Do a catch can . I wouldn't run open filter
I've been running the CFM baffled breather for a couple of months now and see no signs of oil/mist yet.
I kept my catch cans installed, even with the breather. I don't know if it's just coincidence or what but it seems like the catch can is picking up more oil now than prior to running the breather. Again, that could be completely unrelated to the breather, though. Maybe it's just how I've been driving lately or due to the cooler weather, etc.. Just something I've noticed.

That breather isn't like running two breathers on each valve cover. It has a one way check valve in it that only lets pressure out and no flow in. It will only open when both pcv lines get overrun i.e. positive pressure in the crankcase.
Exactly. A properly functioning valve cover breather complete with a check ball will help keep crank case pressure down, while the catch cans will keep the oil separated and from entering into the intake.
Running the CFM's in all vehicles except the F250.
