Bibiki Seashell isnt worth using unless you are 100% postive you are hitting the attack cap.
I would also use Grim over Twilight for the same reason, or if you can get a Byrnie +1 till you can get your hands on Ares or Shadow Breastplate.
Keep in Mind that VIT may be the main mod, but Attack is by far the biggest benefactor for Torcleaver. Like I said before unless you are 100% Positive you are hitting the attack cap, you are better off sticking too attack.
I use two sets.
LR Down:
LR Up:
These are the two general sets I use, altho on higher NMs I will go in favor of my higher attack build instead of my VIT build.
Edit:
Why are you WS'ing in Goading Belt? Warwolf should be your waist option if you don't have your Snow belt yet which isnt hard to get at all, Isgenbind is a joke and your lv 90 Mob.
