New road bike options

h4z2

I have been waited for the end of season sale with a view to buy the Specialized Venge Expert 2014. I am now left thinking is this the right bike for me compared to the 2015 version or the option to buy an s works venge frame and collecting the components. The final option I like the look of is the 2014 Wilier cento1 sr air di2 matt black.

I will be having a test ride on the 2014 venge and the Wilier shortly but welcome assistance and comments from like minded people.
