First, if you have the bucks, the
Pauly Superscreen is a quantum improvement over any pop filter I've ever used. It's amazing (and at that price, it should be).
Second, here's what I do for plosives.
1. Add a steep highpass filter that's
below the range of the "real" signal so the signal you want to keep is not affected by the highpass filter. This won't eliminate the plosive, but it will make the next two steps more effective. The ProChannel's 48dB/octave highpass filter is great for this.
2. Split the clip at the precise place where the plosive starts.
3. Fade in the plosive using the slow fade-in.
By varying the fade's duration, you can dial in the desired amount of plosive reduction. I use the same technique to reduce, but not eliminate, breath noise.
