Lots of controversy there, for sure. If your caps fit tight and your balls arent undersized, id say your chances of chainfire are very slim. Ring of lead is good. I use .457's in some of my Ubertis. Nice ring but your lead has to be dead soft. Not as big of a deal if you load with the cylinder off the gun.
I personally don't care for the lube over ball method. But, I shoot competition and have to do it then, every time. Rules and such. When I'm shooting for practice/fun I don't gob the crisco over the balls.
