I used to be old skool as well, I was very adamant about everything being cmyk/spot and in a lossless format. Software and output devices had progressed so much since then that I have changed my ways. I get so much better results leaving my images RGB when I print to an Digital Indigo or a wide format machine that has an extended gamut. This is all of course relying on well color managed machines and RIP software.

From now I leave everything in the colorspace it was given to me and let the software handle the conversion.
