Nostalrius Begins - Quality wow vanilla realm (1.12)

Hey guys, first0 time rogue in vanilla, and I need help.
I know there are a lot of pvp specs, but can someone go through them quickly, and explain the pros of each. Mostly importantly, a link to the talent tree setup.

example: 21/8/22 - daggers(I think?) www.TalentTreeSetup.com
Pros: good sustained dps

Thanks in advance!
