Have you used ZBrush much before Oz? Are you planning on using displacement/normal maps and bringing him back to Maya after Zbrush?

I ask because I was going to say how I find Zbrush so good and quick at sorting problems that Ive come to the frame of mind that you really dont need to spend too much time in Maya, but, I always have trouble when bringing z-maps back to Maya, and maybe it's because I dont spend enough time there...
