4.6 coolant leak

I have a leak somewhere in the coolant system on my 4.6. Which hose is prone to leak more than the others? I don't think it's my water pump. Its such a slow leak I'm having a hard time finding it. The engine has 150k miles.

Why not, have you checked the weep hole under the water pump to see if there are traces of dried coolant?
