Takebacker's Ultimate Brawler Guide

I'm in my 40's over at the shopping center.

So far, I have been following your guide to a tee, but I honestly have been finding Tornado Upper to be better at Mobing than Corkscrew Blow.

Is there a good reason why Corkscrew Blow is better, or are the skills interchangeable?

Because you don't use tornado upper after 2nd job. You combo csb and double spiral for most of your training in 3rd/4th job.
