This setup works good for a PvM or even in SvS.. If you need a little more FHR may I suggest using duel Spirits (35 FCR is a must on both).. I know some areas in GRushing or Chaos/Baal runs you might want to run 86 FHR or you might actually get better stats off of duel spirits, but you'll be lacking the Res obviously.. Also one thing I've noticed using Act 2 Merc, if you do a lot of Baaling/Chaosing you might be better off with a non eth Infinity to do a little less damage if you get IM but that is a personal preference.
