Handling Frequency of Bull Snakes?

[beaglegod]

Being that this seems to be a species specific subject. I just wanted to know what you experienced Bull/Gopher/Pine snake owners feel is the proper amount of handling.(time and frequency)
I know in the past my Sumatran Blood python I could handle everyday, my Ball Python seemed a bit more sensitive hence I handled him a little less. I have no real life experience with any of the Pitouphis snakes.

Although i dont own any bull snakes many of my friends do and they handle about the same as blood pythons.

Mine are extremely moody!
Both are usually cage aggressive, but there are times when they simply never settle down.
I basically handle them whenever there mood is positive, or when their cages need cleaning.
