SQL Server Performance Tuning with Hypothetical Indexes

I don't generally reblog stuff but pretty much everything in this blog post was new to me. Apparently this is how DTA works under the covers. I knew about hypothetical indexes and DTA, but not how I could leverage them myself.  I doubt I'll ever use this feature (I like to test the actual indexes, not the hypothetical ones), but it's always nice to learn new things.
