Thank you, Aaron. First one to reply to any of my posts :). Thanks.
I did end up tuning the drums. Since they were already recorded, I used Waves Torque to do so and it worked well. One interesting side effect. The kick disappeared behind the bass after tuning. I ended up side-chaining the kick and ducking the bass using Trackspacer (since I could easily control exactly what I wanted ducked) and this brought the kick back out.
I do think the drums sound tighter this way for this song. The client loved it.
I did see the FAQ Friday post as well as Rick's videos on the subject.
