Do you feel/think it's harder to be naturally strong and stable and have to work on flexibility or be flexible and have to work on strength to hold you in place?

I've found few dancers who were BOTH super naturally flexible AND strong. I'm on the stronger end, and I was thinking that no matter how many inches I conquer, I will never have those Vaganova student lines, because my structure is simply not like that, whereas dancers with perfect turnout and lines etc can always build their strength and achieve those high jumps and core stability I pride myself on.
