Did I use the wrong docking port?

[Jestersage]

While there is no way one can go "perfectly match up" in size and etc to the real life, but is it just me that the CBM tunnels are significantly big compare to the SSVP used by Russian Segment?

So say I build a space station. Should the russian segment use the clamp-o-tron jr while the American segment use the clamp-o-tron standard? Or should the American Segment use the SR dock?

This question about how to play the game has been moved to Gameplay Questions. 

Where I do not know the answer, because I have tried that particular mix of parts yet.

For reality's sake, use mods.

For structural's sake, use Sr.

SSVP and APAS are about the same size, roughly 1.2m outer diameter so the 1.25m ports are about right for them.

CBMs are about 2m outer diameter so they're a bit smaller than a senior port.
