I dunno, which would be better shit is probably situational. I full time goliard saio for TP, my DW/ACC body is in my mog storage, I don't feel like digging it out to parse or to do the math. You might lose a hit if you full time the DW body, but if you use goliard instead haste pinion would likely be better.

Id say the difference would be neglible either way, while you might lose a hit, you are going to gain almost a full hit.

Just quickly punching it into my calculator (i won't bore you with all the math) I got 23.23 seconds to 100TP (on average) using Blau + Joyeuse numbers (I know them by heart) for Pinion + Raja's, and 22.56 seconds to 100TP (on average) using just Rajas. So its about a 2.4% increase in weaponskill frequency, assuming you WS the instant you hit 100TP otherwise the difference will in the end be negligible.

With goliard you are looking at a 2.4% increase to time to 100%, so in the same vein if you hit at exactly 100%TP you will benefit, otherwise it is negligible.

So if using DW body - Tsting is your likely best bet (1% increase from attack would need to be +6 with 600ATK) unless you have capped ACC (in which case Goliard would be better than the DW body)

If using Goliard body Pinion is statistically the best bet.

But in the end it is a matter of small %'s that only matter when you use WS at exactly 100TP (well when you break the 100TP barrier). Otherwise it is a negligible gain.
