ive owned a few z's on my first z i ran the catch can setup, it was quick and painless method but cost a lil bit more money than the filter setup...i found the catch can to be a bit messier only because i had to find a spot to hide it then clean it up every oil change...the mini filter route ran fine for me, i feel its not only cheaper (not talking big buck here but still cheaper) but just easier to maintain :P
