Velium Swiftblade VS CSS + SCHW

[cactus]

Hello my fellow auto attackers!

I'm trying to determine which weapon/haste combo would be a better overall DPS setup for my twink Barbarian Rogue I plan on making soon.

Setup #1:

MH: Serpent's Tooth (13/27)
OH: Crystalline Short Sword (12/24)
HASTE: Silver Chitin Handwraps (22% Haste)

Setup #2:

MH: Serpent's Tooth (13/27)
OH: Velium Swiftblade (5/24, Haste Item)
HASTE: Velium Swiftblade (36% Haste)


Would the additional haste and thus increased backstab refresh rate equate to a larger DPS gain than the better ratio of the CSS? Let me know what you think.

Thanks!
