Sounds like you already got her figured out, but I will add this little bit of wisdom: Make sure you clean new molds with some mineral spirits
before you smoke them......smoking molds with a thin film of oil on them (from the machining process) doesn't allow the carbon to lay down on the mold; it 'float's on the top of the oil, and makes it harder to get rid off. The result is also 'wrinkly balls" (sounds like a disease, don't it!

) as well.
.....now that I have added my 2 cents, I'll shut up.
