Getting ready to desposit $50 into full tilt. What are your opinions on the best way to make that grow with the least risk?

I'm thinking about:
-microstakes cash games
-$2 sitngos
-$2 headsup

Which one of these do you think is the easiest way to do it? I've never played a cash game, but I have read up on them. I've played a lot of $2 sitngos, but that was on bodog and they were the beginner sitngos where 5 places are paid out. I am fairly good at headsup.

I'd appreciate any insight.
