I use clay pots. They breath well, and the roots do not stick, given you don't use a ridiculous shaped pot they slide right out. When it's windy the added weight is a plus. I water every evening after dark when it's hot. I think it helps to cluster pots together or cluster flowers pots around the big fig pots so they get shaded and don't collect too much heat throughout the day when temps are high. This year I am going to wrap burlap around my stand alones once the temps get high. Partial burying also helpls control pot temps as well.
I invested in something called a "Pot Lifter" on Amazon. It requires two people, sort of and adjustable sling with handles which grips the pot as well. AWESOME!!! I love it, my wife is small and not athletic but she can easily help me move my largest pots. It is rated up to 200 lbs, and can be used to move any large oddly shaped object. For example, stump logs, giant pumpkins, landscaping rocks...
