70pvp Reward question.Follow

Hello I've done pvp for a long time and almost always my mh dagger was a dagger I got from BG's. I'm level 70 now and I was wondering what would be the best thing to get with moh and honor for a level 70NE Rogue. I was thinking the shanker or shiv but there are alot of 70 daggers out there that are very nice. Any suggestions?
