THF/MNK gains martial arts, and the difference in skill is not noticable until higher levels with h2h, so if you do sub MNK always use H2h, SA Combo also stacks(although only first hit). I prefer sword though due to skillchain combinations...THF/BRD inside valkurm is probably not that bad an idea also, once outside ditch it. THF/DRG and /RNG 20 til 30 is also awesome, /DRG with Jump/ATK Bonus, and /RNG for Acc Bonus and /ra WS(if you got it skilled). Afterwards /WAR is probably best until 50 where /NIN is debatble with /WAR, OR if theres fast running mobs where you can actually put Utsusemi for use.

Koroloka: anything on the bottom of the stairs XD Probably aggros.
