The spins have magnitude 0.95, are parallel to each other, but are anti-aligned with the orbital angular momentum. This simulation is described in a publication in Phys. Rev. D., in press. The paper can also be accesed at arXiv:1010.2777.
Note that aside from corrections that become important only near the time of merger, the spin function χ and scalar curvature R should agree well with -2Bnn and -2Enn, respectively, where Bnn and Enn are the horizon vorticity and tendicity, respectively.
Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run twice as fast as that.
