I would not worry about lot to lot inconsistency in your lead. It will be close enough each time if you do the same things each time, as far as what you toss in the pot for alloy.
I have who knows how many "different" lots of lead. They all work the same for me so far.
Whatever you are willing to put up with, is exactly what you will have.
When your ship comes in. ... make sure you are willing to unload it.
PAYPAL, sucks and I will never use them again. I recommend you do the same.
