Benefits of hybrid attacks
I was wondering what is the actual use of hybrid attacks where you define a left and right sides. The actual attack mode is extremely slow compared to other methods and I often times just use this mode with --stdout, output to a file and then run a dictionary attack with that file which is (in some cases) x1000 in performance.

What am I missing?
Depends on the use-case. With a large enough wordlists and masks the speeds are better for fast hashes.
