Hey Ridge, when I used to record a fair bit I would rarely mic the bottoms. Typically I'd use 421s on all.. occasionally AKG414s on the racks, just depended on the music really. Then 87's on the overheads.
The times I would add bottom mics were usually when I had more time for the set up. 🙂 Just be mindful of phase alignment when using the bottom mics.
Hope that helps
