I can't imagine putting the overheads out of phase on purpose all the time. Thats kinda crazy to me, but YMMV.
Heres one that seems to be making people happy lately, and again, YMMV. This guarantees snare and kick phase and allows for a wider pair than an x/y coincidence will get.
Sit at the kit, place two drumsticks together lenghtwise, straight up from the center of the snare. Put the 1st diaprahgm right there. Next, keeping the sticks in the same double length style, lean them to the right (or left, depending on where the floor toms go) over your shoulder some, and down lower than the other mic.
Now, using the right sholder mic as the "centering mic", wearing headphones, hit the snare and kick until they are in the center of the image, adjusting the right side mic angle until it is right. This will do a few things... 1) good phase for snare and kick 2) follows the actual layout of the kit, so the lower toms have equal volume in the mix. 3) The cymbals are somewhat off axis so that they arent so damn dominant in the mix, you get a better mix from the very beggining, and you probably wont need a snare or tom mics because of the close proximity to the kit.
Also, measure the distance from center of kick to each diaphragm so that it is in good phase. And yes, use a tape measure or some other measuring device. No kidding. (Thats what the sticks did initially, measure distance). When you use a kick mic, phase should either be reversed on the kick or both overheads. You may also want a mic on bottom of snare to get a bit of snare sound, which should also be reversed against your overheads.
You may also want to TRY using the same distance from kick center to overheads as kick center to kick mic. Kinda far, but micing far can be quite nice. Try it. Its super easy and fast once you get the feel down. It looks weird, but oh well. You may have to adjust some distances in acoordance with the drummers playing style.
