I agree it's not perfect but still overall impressive for it's time period. I think the blacked out room + large HP screen with the projectors at eye level for max gain in making me overly sensitive to shifts in the black floor.
Once the RS600 arrives, it might be time to downsize for a while and let others enjoy the DC4 Planar + the RS46 (~45 ms lag, not too bad compared to 130+ today). The 30K will stay unless I am floored with the JVC's 3D.
if only they can tame the flicker a bit I would be ok with it since the x-talk is mostly under control.
Are you planning on picking up a spyder meter and playing around with the autocal?
