For me it's been more of  a viability question.  The one weapons pack I've done separately (Sickle Heavy Shields and Weapons) did quite badly compared to the armor set it goes with.  The Sickle Whips did all right, but they were a massively difficult EasyPose project.

I'll be doing some ninja weapons before too long here, but that's mainly because Shadow Warrior is fuseling's baby, and what are ninjas without their shuriken? ;)
