The sheet metal ones are the ones I see used the most, I don't know if you have to worry about snakes climbing up the pole since it's mounted in the water.

A friend near Sulfur Springs Texas has some Mexican Whistlers using his along with Woodies using others. He found that in addition to the metal cone type guard, he had to use a snake guard. His posts are on dry or semi-wet ground.....
