Hey I've always panned drums as wider as possible which actually means OH and rooms at 100% LR. With a little bit more experience and more proper listening to pro mixes - in Metal genres at least - I realized that the drums in mixes I like the most are in general "not that wide" except maybe snare verb and the toms. For me, a good example of this is Mnemic 'Passenger' album, mixed by Tue Madsen. So I tried to do so and the result is that the drums sound more focused and there is more space for rhythm guitars. I feel it can give a nice 3D perception when it's well done. Also, I used to play a lot with stereo room mics but, in the same idea, I tend to give more and more advantage of mono room track and keep stereo room to give some "texture" or "pump" to the OH. Sure, there is no good or bad rules as it depends on what we want to achieve but I'd be curious to know your thoughts/tastes about that and your usual methods.
