Store TP and 450 delay questionsFollow

Ok thanks to Abyssea I have managed to literally run out of things to merit. I'm sitting with Mnk, Nin, Blm, Bard, Thf 90 with full merits as well as 84 rdm(20/20 merits on it also). The problem is I have a Brew addiction that demands to be fed. I blame the inner Mnk in me too many late nights drinking with Oggbi. I cannot bring myself to waste experience points just sitting in abbysea with capped xp/merits just getting cruor. So I have turned to Sam.
I have managed to get my Sam up to 84 in the past few days from its previous level 69 where I had been leveling it for Colbri parties pre abyssea.

I had always only glanced at the X-hit builds before because my previous jobs don't use it ( Mnk, Nin, Thf) Now that Sam is only 6 levels away from 90 I'm wanting to make sure I'm headed in the right direction.

My current weapon is an augmented
Yukitsugu
(Great Katana) All Races
DMG: 84 Delay: 450 STR +3 VIT +3

Augments Damag +10 and +3% Skill chain damage.

It's no ultimate weapon but will be servicable for now.

Is the following math still correct:

Sam Store TP traits +25
5x Store TP merits + 10
Total of +35

I found this chart listing delay 450 weapons and Store TP needed to reach various X hit builds:
delay tp/hit 8hit 7 hit 6 hit 5 hit
450 11.5 9 25 46 74

Looking at 6 hit since 46 - 35 only leaves me needing 11.
Rajas - 5
Brutal - 1
Rose Strap - 4
Unkai Kabuto +1 - 5
Total - +15

Would easiy cover that. I could even drop the Rose Strap in favor of something else. ane recommendations on altenrate Straps? Through various questing NM's I already hade Unkai Hands, legs, feet already completed. I see definite improvement to go from Walmart Turban = Unkai Kabuto+1 for head slot. I have Byakko Haidate already, I'm not wanting to go from 5% hates down to 4% haste on leg slot, but the Store TP +5 makes me wonder how easy/hard it would be to get to 5 hit.

I'll mainly be using Sam in Abyssea. Is it even worth it to gear toward x hit anymore?
While Xping I've been using Razed Ruins, Apoc and Perfect Attendance ( PA because most of the alliances I've been in had been understaffed with healers it seems)

For TP gear
Strap - Rose
Head - Walmart Turban (working on Unkai head as soon as possible)
neck -Peacock Amulet
Body - Hauby/Osode/
Legs - Byakko
Feet - Fuma Sunate
ER - Brutal/Kemas
Rings - Rajas/ Ult ring
Ranged - bows/arrows ( end up pulling occasionally for some reason)
Belt - Swift
Back - Cerb mantle

With Triple Attack from Apoc is /war still the best for overall damage output?
what about /thf for SA Weapon Skills? or just worthless overall? we don't have a critical hit WS, so wondering if forced crits from SA or possible TA can do anything?
How does haste samba from dancer at 90/45 compare to /war?

but TL;DR.

No clue what that means, but ok

Re weapon - hmm, I though I saw a post by Milch that Damage 94-95 was the turning point at which Hagun fell out of favor. Hagun are only 20kish now, I'll consider getting another one. Right now mainly Soboro for XP parties since WS is generally No Thanks in general pickup groups its seems only in LS XP parties do people seem to have knowledge of lights and such. And I need still need Skill Ups on GKT anyway.

Thanks for for armor list, Just finished Unkai head +1 friday, putting me at 4/5 for +1 set. Think I'll just skip goading belt. as much as i dread -50 to elemental resists bull whip would be easier to obtain and faster. I wanted goadig for my nin but with brew Twlight belt should be in my near future for nin/thf/blu. Mnk still enjoys my black belt.
