Need some Theory Crafting help

[Keio]

I need some heavy theorycrafters help here, I would like to know would it be better to go with Poleaxe or stay Mace at this point in the game.

Mace
Ironsoul
3158ap (4500-ish raid buffed)
34.27% crit (43% raid buffed)
7.5% hit (we got shamans with that 1% hit yay)
12exp (3+exp cause I'm human)

Poleaxe
Relentless Edge
3154 (again 4500-ish raid buffed)
41.32% crit (50% raid buffed)
7.5% hit (same as before)
12exp (negitive -3exp human again)

I am Arms 56/15 - Mace or Poleaxe depending on the day

the question I have for you guys is simply this

74%ArP (94% with sunder) 42%crit - Mace Spec'd

vs

51%ArP (71% with sunder) but 50%crit - Poleaxe Spec'd

Ironsoul is my Mace
Relentless Edge is my poleaxe

I've spent weeks playing with it raid and I cannot find a cognitive answer. Is losing 21% Arp worth the increase of crit from switching spec's

Lookin for help

thanks

Poleaxe.

Reason - ArP is capped at 100% outbound (this does not include debuffs on the boss, just what's on your character screen). Crit, however, (for practical purposes) is not. Not to mention +5% dmg on half of your attacks = omg drool.
