I just uploaded a couple of files to the Home/Upload & Download Files section.
One is a chart Jeff sent out a week or two ago, for easy classing. That will help you figure out the right category based on what mods you've done.
The other is the 2012 rulebook, just scroll down to the section on whatever category you figured out from the chart, and it should give you the rest.
My AW15 goes in STS, YMMV.
