Really not much we can do without some actual numbers. Post a parse or two (preferably WoL) so that we can see your rotation etc.
One thing I would mention right off the bat is that you seem to be hurting yourself using Grim Toll having hit up around 261 when you only need 164+ as fury. I would use the Scorpion or Mjolnir if I were you. Also I would replaced that ranged weap since it is also itemized for hit when there are better options out there.
