i have recently stopped using a pop-filter for most sessions.
i think for hip-hop, or loud rock, the benefits may still outweigh the drawbacks.
but i was about to throw down several thousand for a different vocal mic after growing displeased with my Mojave MA-200.
the other night i did a vocal session with no pop filter and the mic sounded like a million bucks. easily the best vocal sound i've recorded in a long, long time. i've done other sessions with the same singer through the same chain (API 312, Purple MC77, Digi 192) that didn't sound nearly as big/full/warm/awesome/natural/whatever. totally happy with the mic now.
