I face lather exclusively and generally have no problem with watery lather even doing 4 passes as long as I have loaded the brush with enough soap in the first place. If I did not load enough I simple go back to the puck for a few more swirls of soap so it is not watery. Whatever is left in the brush at the end of the shave gets rinsed down the drain.
I do know that some members will squeeze what is left in the brush out to put on top of the puck instead of rinsing it down the drain.
