Which rogue spec to choose?

Holla reddit, currently I am leveling my rogue and just reached level 90. I got around 70k apexis crystalls on my main and I thought of buying the token for the empowered itmes of tanaan to boost that rogue. Sadly, the rogue specs differ in itemization. Which spec would be the best to choose in order to get started in normal HFC, so I can focus on one spec? Thanks for the answers =)
