Colnago CLX replacement

LoufromMat

I'm thinking of buying a Colnago CLX and just found out that it is being phased out in favour of the C-RS. Reading the Colnago site and some reviews it is my impression that the CLX is a bike right below the V1-R, where one review says that it is difficult to find differences in the ride between the two. As for the C-RS it is defined as "entry level to Colnago carbon bikes". I'm looking for an upgrade (meaning stiffer/lighter) from my Pinarello FP-Quattro. The CLX sounds like one but the C-RS sounds almost like a step down (plus I don't like the design as much). Anyone knows if there's a difference in "raciness"/stiffness between the CLX and the C-RS?

Thanks
