i prefer blood draining or mongoose on my tank weapons. i use blood draining on my ardent guard and use it when i need some extra eh. and i have mongoose on my threat weapon which is marrowgar 10 heroic mace to give a little more threat via crit/haste as well as boost armor and dodge a tad.
you are over 263 hit which is the cap for non-duel weilding so really your 25 hit is going to waste.
whatever you do, never get blade ward. there are plenty of posts on here detailing why with the math behind it.
