Okay, let's help everyone out here and tell us what pots you are all using that have the spouts.
I have looked at the smaller Lee Pot with the pour spot and it looks like it would be a pain in the arse to flux anything in there. The larger one looks like it would be more open and easier to skim and flux in but I could be wrong here.
One thing I have also never heard is do you leave the lead in the pot or pour it all out when done for the day?
I love taking my kids fishing, now if I could just manage to fish at the same time.
