If you are bouncing using a bracket is superfluous. Aim the flash toward a wall/ceiling junction and let ETTL find the exposure.
I have probably 5 brackets I've purchased over the years, they all are collecting dust. I use an ETTL flash bounced for probably 98% of my shots during a wedding. The only time the flash is aimed at the subject is outside for fill.
With a little practice and paying attention to details you will learn that ETTL works great, providing you understand its not a magic bullet. i.e. you still have to think. 
I use a foamie thing (Neil vN made it famous as the "black foamie thing") Its main purpose is to keep light off of people in front of the camera so that the bounce light is dominate.
