strange SK weapon question!

[Seeatee]

i have been playing my SK again, as a tank I know it is my role to dps as well as hold agro, that being said my primary concern is holding agro, I do not have the money to get a haste item and probably will not for some time.

would it be a waste as a SK to invest in a weapon like a SSoY or a sarnak war hammer to use for tanking? to help generate extra agro? as far as I am concerned you can never have too much agro, or would i be better off going with something like a MoSS?
