Are there any significant differences between a Stacked Leverage, Label Leverage and Rev Leverage drillings? What are the advantages of each, and are there any preferences? Any help would be appreciated. PS. I'm drilling up an Epic Odyssey, and at first I was thinking aboput 6" pin, but my pro shop said "let's go crazy and drill something for heavy oil."

It don't mean a thing, if it ain't got that swing.
