What's higher DPS

[heartbrand]

I have the following weapons on red and am trying to determine which will have the highest DPS output. Parsing is unreliable until thousands and thousands of attempts.

1) Jaelen's Katana
2) Willsapper
3) Blue epic


I've been thinking katana and blue epic despite the worse ratio of epic vs WS are better due to higher slashing skill for warriors and the atk buff of the blue epic, but am not sure. (The regular stats don't matter I'm 255 all)

For aggro I've been doing WS / katana but not sure how big the threat of strike of the chosen is, though for raids im malleting anyway.

Thoughts?
