All these references and so little knowledge. I am certain that will change. So I am looking at 20 inch bars and chains by different manufacturers, for the 576xp. I see pitch, bar thickness and drive lengths. I see 20 inch bars with 70 and 72 dl. Wouldn't a pitch and length determine the dl?? Set me straight. And I wouldn't mind some opinions of bar models that are good buys either.
