Well let's think about this for a minute.

There are 640 acres in one square mile.

That would mean there are five deer on that first300 acres.

That also means there are 15+ deer on the opposite 300 acres.

I would take the higherpopulation acreage.

Just because there is little trophy potential [initially]doesn't mean that that potential couldn't be increased.

Theres a lot more to consider, but keeping things simple, thats how I would go.
