Takebacker's Ultimate Brawler Guide

I was looking at your 2nd job build, and I think there might be other ways to do it, since max HP increase is now %, you can add it whenever you want, so it's not so important right at the start, also, I heard or read somewhere that for best damage on training, BSB>CSB, how true is that? cause if it is, a more viable build could be around:

30: +1 Corkscrew
31: +1 backspin +2 mastery
32: +3 mastery
33: +3 booster
34: +3 booster (6)
35-37: Critical Punch
38: +1 Critical Punch (MAX), +2 Knuckle Mastery
39-42: Knuckle Mastery
43: +1 Mastery (MAX)
44-49: Backspin
50: +1 Backspin (max) +2 HP increase
51-53: Hp increase
51-55: Corkscrew
then HP recovery, barrel and extras in double upper, but that's more or less the idea that I think I'm doing for my brawler in KMS, ideas, opinions, help? o.o

i was under he impression that double upper didn't suck anymore and was spammable
