Look at the geo chart above, 2006 Six13 was offered in a 53cm as a frameset only which is how I purchased it. The 53 was slightly large (standover, seat tube..) The top tube was about right as I have a long reach, I had a 110 stem on there and just about slammed down
I stand corrected.
So, the geometry can be compared directly to the CAAD10. You had a decent length stem for that size and you didn't need more drop either, it seems. If the only problem was standover, that's a lot like toe overlap - not really a problem, but you do have to think about it. The 50 would net you a bit over 2cm of standover clearance at the expense of adding 15mm of spacers. Reach doesn't change much; taking into account the steeper seat tube angle, you'd need to go to a 120mm stem, no more. The 52 would give you almost 1cm of standover as well as 1cm of spacers, and you could keep the 110mm stem or go to 120 depending on what feels better.
