I don't have the specs in front of me but I am not sure what you gain by spending the extra$$ on the comp for 2011. If you are planning to ride hills I believe the Apex fits the bill. Now that Specializes went to the SL2 frame for the Elite I think the entire package gives the biggest bang for the buck with no downside. The SL2 was last years S-Works frame.
I'll post photos when I get back to Beech where the bike resides.
