Roval CL 50 vs Giant SLR 0 Aero

[mdavis501]

I am considering upgrading the wheelset on my Giant Defy Advanced Pro 0, which comes with Giant SLR1 and uses the pawl based driver system. I'm considering Roval CL50's or Giant Aero SLR 0 42's.
On one hand I like the idea of keeping the same brand and I know that Giant SLR 0's are great wheels. However, the Roval's specs, from what I can see, seem slightly better. Would love to hear from someone who has ridden both (although I know this is a very unusual comparison, since few riders other than Giant riders buy Giant wheels, anecdotal info only).
