Tiger Golden Master via instaDMG

Does anyone have personal experience creating a Tiger 10.4.x Golden Master image via InstaDMG? If so, please are you willing to give any advice. Are there any PowerPC vs Intel issues that one should be careful of? Is the best course two DMGs, one for PPC and one for Intel? If you are willing to share a Catalog File for InstaUp2Date, for Tiger, with updates, that would be wonderful. I've been using NetInstall and Deploy Studio, but I'm a newbe for instaDMG, and feel a bit lost. And I need to jump in quickly and come up with a working Tiger GM. Thanks in advanced for any help.
