Tashalatora for me as well. Kalastar Monk/Psywar with Ectoplasmic Fist, Mighty Arms warforged graft (w/Battlefist), Improved Natural Attack(or Fanged Ring), Expansion(+2 sizes), Shape Soulmeld(Totem Avatar) with the Open Chakra power to bind it to Shoulders...
2d10->4d8->6d8->8d8->16d8->24d8
Add on Vampiric Blade and you heal 1/2 of 24d8 with each attack, or an avg. of 54 hit points per attack.
Monks aren't (that) bad when you have Eberron.
