You are incorrect in one aspect: Your 200mm is 200mm regardless of which body it is on. The focal length does not change, only the field of view. If you were to superimpose the APS-C shot on top of the full frame shot you would find that the magnification is identical. I find that APS-C is best for shots where your subject matter is a relatively small portion of the photo. Wildlife, BIF, some sports, etc. Otherwise, I prefer full frame. For full frame I find that 3 lenses cover the majority of my shooting: 16-35, 24-105, and 100-400. Beyond 400mm the lenses tend to be quite pricey, quite heavy, or both. If I need a bit of extra reach a 1.4x extender does the job. For a FF one of the handiest all-around lenses is something in the 24-105 range, IMO. Because full frame is normally superior to APS-C in low light/high ISO situations you may well find that the more expensive fast lenses are not as important, depending on your shooting.
If you are going full frame I suggest you get one all-around lens, such as a 24-105 (popular with Canon. Not familiar with Nikon), and see where your shooting takes you from there.

Appreciate your thoughts, but your analysis goes further then I think I need. Sorry if I am not explaining correctly.
Going back to my original post, IF I took 100 pictures whose data read 200mm focal length and 300mm 35mm focal length (this is from a crop camera), but I know that in the future I'm going to be shooting with a FF, should whatever lens I purchase have a long end of 200mm or 300mm.
Just trying to use past shooting history to determine long end mms.
