Least complex sicilian opening?

I am replying to this old discussion with a question for Pfren and Poucin if they are still following this thread. Pfren makes a really solid case for why class level players should not play the Sicilian. I am convinced. I will stick with ...e5. 

However, since the Sicilian is played all the time by club players, how should an ordinary club player respond when they play 1 e4 and their opponent responds with ...c5, which is usually what happens at all levels of play? Is it better to save study time by learning an anti-Sicilian, or is it better to "call their bluff" and play an open Sicilian?
