I was watching WiiGetItDone's video today and there is a step that I consider could be easier.(not very different in fact)
In the step of converting the iso to disc ex (at 2:35) he first convert the iso, then browse the created folder, rename the iso inside, open the iso, shrink it and then create a new iso and delete the previous one.
What I do is create the iso with cleanrip, then I shrink this iso(same way like in the video) and disc ex it. The created folder will be already shrinked. It not so much different than the procedure in the video but it might be a little easier I think for those people that don't want to browse the folder contents.
