filter media bags - are they all created equal?

[shamrock]

hey

simple question for the knowledgeable. i've spotted various filter media bags - some with velcro, some with zippers... would you choose one over the other? i'm guessing the velcro over a metal zipper?

thanks

I prefer the ones with a draw string closure.
