Agreed, most buyers/owners go by bar length. If the saw comes with a 20' bar then they automatically presume the powerhead is capable of hauling the chain around it. I have had many argue that a Poulan box store saw with a 20' bar would run any of my Stihls with a 16 or 18" bar into the ground, man were they in for a rude awakening. Should see them reel when I pull out a 066 with a 32" or even more so when the 070, 090`s come out with 5' and 6' bars....LOL
