Who to start for week 4?

Between my AD and flex position i have 3 choices: Adryh (GIA), Pepiinero (GIA) and Woolite (ROC). I fully expect ROC to have a great week as they're against two of the worst teams in EU, EL and SK, so i'm pretty convinced on starting woolite. I'm just having a hard time deciding between Adryh and Pepii. Thoughts?
