Most of my fees are 1 or 2 sat. I have it set to minimum.
I have recently set my fees to 0/0 for some of my channels because they become totally unbalanced.
When your channel becomes unbalanced, you can reduce the fees on the unbalanced side so that you will receive transactions on the side that has a low balance.
You can also use dynamic pricing so that as one side gets low, the fee rate will change to encourage transactions to be routed to that side of the channel.
