The way I pan is in a way that ensures that the stereo image stays clear, I want the OH to be the strongest part of the sound, however I really need the snare and kick to sound direct, so those levels will be realtively louder (about 3db) than the OH. Because I am trying to capture everything in the OH the overall pan of items like the HH and Toms are towards the center as that is an effect of OH mics and because they are reversed panned to audience perspective from the rest of the kit, hard panning the direct mics doesn't make those close mics sound hard panned, it actually makes them sound truly panned as if you were really there.
One of the cooler effect is in the HH, because the OH is making up about 60% of the total HH (and tom) volume, having the HH panned hard left in the opposite direction of the the OH's pickup of the HH, you get the phasing and separation of the HH. The HH will sound about 50L however most of the sound on the right speaker is all ambient while the close mic is a volume supplement when needed helps make the HH sound ambient with its own space and allows it to really cut through the mix without actually hearing it. I have noticed this effect a lot in many commercial recordings, the separation of HH mics helps add a 3D space to them. And the same thing happens with the toms, but they will come out sounding huge and really atmospheric.
