Starcraft 2: Giving it another try

After two months of living in Germany, I've finally bought myself an EU account. I have not played this game in months. I do not even remember the last time I played a 1v1.

Since I have a bit more free time now (only going to uni 6 hours a week), I decided I should give 1v1s another shot. Challenge myself, see if I can escape my bronze-noobness. I feel like I'm starting to learn the game all over again because it's honestly been that long since I last played.

Last few months of playing, I'd been picking random. But I think, if I want to take ladder games remotely seriously, I need to choose one race to focus on. Question is, which one?

It's such a hard choice, because I actually really enjoy playing random. 

Terran - as my previous race, would be the easiest to get back into. But I want to try something new.
Protoss - seems to be one of the easier races to play, especially if I want to concentrate on becoming a macro player. Protoss late game just owns face.

Zerg - It's the most fun to play I think, but also the hardest and requires a lot of multi-tasking. However, it's my chosen race for Heart of the Swarm (when it eventually is released) and I also have friends who can coach me in Zerg.

My head says Protoss, just because I think it'll be easier, but my heart is telling me Zerg...
