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 mobility. It's second job, it doesn't really matter.
