From GR it is totally clear that photons with higher enery have both more "heavy" and "inertial" mass. However the term "relativistic mass" isn't liked there either. As the truth is in the equations as a professor of mine used to say, wherever m appears in an equation it means rest mass. You won't find any "relativistic mass" there. And it helps to avoid confusion to keep it that way.

The term "heavy" mass is not clear. I just Googled it, and it seems that you are the first to use it, so could you explain what it means, please?
I'm advocating use of the term "rest mass", and I'm not advocating the use of "relativistic mass".
