Hey man hope all is well. I am currently running the Cat. Since though I have myself been worried about the water sep so I have two Donaldson with the clear bowl on the shelf waiting to go in. I figure the Donaldson is only a few micron worse but you get the h20 sep. They are both cheaper than the recor which is nice. Sorry on the smartphone here if its choppy. Drop me a text tomorrow if u have any other questions.
