Looking for real life user stories with Optimizer

If you have been using SQL Optimizer (in Toad for Oracle Xpert and higher editions) let us know how it is working for you, times that you have found it useful... basically any real-life stories around SQL Optimizer. I will give a $50 Amazon card to the top 5 stories we get submitted and can use in our blogs and other marketing materials (you can remain anonymous in those stories if you like!).
