What do you think I should use

Or Ik maul? and what do you think i should put in the maul? All amethyst or maybe 2x jah and 2xamethyst?

You need to hit 163% wias on the maul to get the same speed on it for fury (4/3/3/3 fpa) or 133% wias for a 5/4/4/4 fpa fury. It would certainly be better with four über amethyst and I'd prefer if over that craft with 3 amethysts and a jah aswell.

But over both those, I would chose a executioners justice with a über amethyst or a 20 ias +%ed in it. That would hit 6/4/4/4 or 5/4/4/4 fpa fury with high ctc decrep, massive dmg, skills, res etc etc.
