Best South Cascades Hikes

I am very familiar with the North Cascades and Alpine Lakes Wilderness Area, but much less so with the South Cascades. What are the best half-dozen hikes and backpack trips in the South Cascades. I can't get a good read on the top tier trips by reading the various hiking books. Some that leap out are Cougar lakes in the William O. Douglas W.A., some of the lake trips in Indian Heaven Wilderness, and perhaps Norway Pass. What else??? Thanks.
