Think for yourself.
Say you have a given tube, it's diameter and it's length.
Now increase it's diameter. You need to thin the wall thickness, of course. It's stiffer.
Now decrease the diameter. You would need to increase it's wall thickness, to keep the same weight. Now it's got slower REFLEX.
I am NOT negating your conclusion.
The reasoning is NOT 100% correct because
frame A can different from B by the fact that both of them are partially empty
or filled ,say,with a foam like material of a varying density.
If my explanation is NOT very clear I will try to do a better job tomorrow.
Have a good night
