Has Anyone Treid the Mastering Templates?

Hello All, just curious.
 
I have tried them.  I usually export my wave files into Audition and do some minor tweaking in there.
 
But one day I decided to export a wave, fire up the "Smooth" mastering template, and then imported the wave file back into Sonar.  I'm not sure if that i how they were meant to be used, but that is what i did.  I tried it a couple more times on other mixes.
 
I thought it was pretty neat.
 
Anybody else?  How do you use them, if you do use them?
 
Out of habit I still go to Audition, but when I get more time I'm going to fiddle around with them again.
