Managed to get a bit more haste and now haste overpassed multistrike and mastery raised as well. Currently based on my simcraft, ST:
Sitting at about 900 haste. My guess with this stats the PvP shoulders are almost BiS with hc progress and haste/mastery or haste/vers are good combo's to get on gear.Strength (4.4) > Haste (1.76) > Multistrike (1.69) > Versatility (1.55) > Mastery (1.44) > Crit (1.38)
