Catch can questions.

I am looking at catch cans for my blow through s/c setup. I need help on narrowing down my options. should I go for a closed duel input single output catch can style using both valve cover ports and attaching the output to the pcv input on the throttle body?

Is it recommended to only have the passenger side filtered and the driver side vented to atmosphere? If i vent to atmosphere on the driver side will there be a smell and/or oil in my engine bay?

Should I be pulling vacuum from both passenger and driver side valve cover vent ports to ensure proper operation?

I am looking for any insight on their own setups/recommendations on catch can setups and components.

Thanks in advance.
