2.6 HOWA BF VS. Crit Dagger (Poison) BF

Hey guys i wanted your inputs on what you guys think would be the best for Blade Flurry. I am currently running a HOWA Blade Flurry Assassin and i can say that i am pretty impressed, but everyone that i have seen running Blade Flurry, they are running Binos based.

Would a mirrored phys dagger be better than Binos?

Any input would be awesome!

Thanks
