Ok, thanks.

I guess that means that if i don't want to take E forever i shouldn't grow 'em beyond what my body can naturally sustain with its own estrogen and perhaps some added DHT blockers.

it doesn't work that way, if you don't want them ending up sagging so bad they look like flaps of excess skin, you will have to keep your e-levels higher than that is male mode normal for you.
