Mind made up.

I wish I knew more about numbers. The DC is the 52cm frame, no idea how the apollo would compare. I would say the DC is more stable though, comparatively. I went to party on the weekend on the apollo, since my friend didn't have paniers yet I loaded all our beer/snacks into the milk crate. I had to stand up to climb a hill and almost dumped my bike XD

anyway, we'll see how the longer stem works for me. 10cm difference is a lot of cm...

Are you sure it's 10 cm and not 10 mm? Most stems are measured in millimeters and it's common to go from, say a 90 mm stem to a 100 mm stem.
