The Carbon one looks way better, but the tuned length stacks on the Fast may mean it's function over form... though I wonder how NA and differing boost levels affect the ideal height differences of each stack.

 

Another negative of the TR carbon design is the cast lower part. Heat soak city....

 

zero issue or concern at all.
