Time Atac Pedals

Ok guys this will be my very last post on the subject of the matter. I went into my LBS to look at the Time Pedals they had both the Roc ATAC S and Roc ATAC Carbon (think they have been discontinued this year) in stock and fairly cheap with a price difference of 7 sterling between the two.
I could also get the XS model for 3 pound difference online, but heard people say that the XS are harder to engage and disengage?
Think I should go for the 2010 Carbon Pedals?

Internet wisdom favours the Roc ATAC, not the XS, and carbon is the fastest materia. Get them.
