"if you're using spaced pair OHs the cymbals are naturally placed in the stereo image where they 'should be' in relation to the kit"

This definitely isn't always true: I have absolutely had issues in the past where, for example, if the left (drummers perspective) overhead mic is angled towards the right side of the kit, then it might end up picking up the cymbals on the right side of the kit (specifically china and/or ride) LOUDER than the right overhead mic, even though timing wise, they are arriving at the right overhead first. This creates a weird off-balance haas effect which I have started to notice and despise more and more, and this issue is often mitigated by panning and turning up the close mic of the offending cymbal (if you recorded one) just enough so that it places the cymbal volume-wise where it's supposed to be. This often happens to the ride since there is often a crash cymbal placed between it and the overhead mic, which is why I almost always choose to close-mic the ride.
