Caad 12 size?

Hi
I'm looking to buy a used Caad 12 and got the option of the 50cm and 52cm version. I'm 173-174cm and flexible and usually should fit a 54cm but it looks like the Caad 12 is on the bigger side. I've looked at some pictures and it looks like you have to go down a size or two to get some seat post exposure.
Unfortunately I don't have the possibility to try the bikes. Therefor I'm asking for you opinion and maybe some of you also got the actual bike.
Cheers

I would go with the 52 given your height, with the Cannondale's your still not going to get a massive amount of post showing.
Quite right the stack and reach figures for CAAD 12 are bigger than the CAAD 10 for the 54.
Do you have the stack and reach figures for your current bike?
This may give you some consideration towards the appropriate size.
So if you do want a slightly more relaxed reach then get a smaller frame, you can always get a longer stem. Can't do anything with the bigger frame.
