Using your P Lyte, Jimmy? And... more relavent to the discussion, which mic?
I've heard good results at the local clubs when competant sound guys are using an AKG D-112 on a bass cab, but I've never tried using one myself in any kind of controlled situation. One of the salesmen at Long & McQuade recommended the Beyerdynamic M99 (I think...). I'm pretty sure that's another kick mic, but he swore by it.
When I'm playing out I'm usually just happy to see the soundguy put ANY kind of mic on my cab, period. If he knows what he's doing and is in any way worth his salt as a sound guy, he'll make it sound good regardless of what's there.
