Well Said. Especially going from pro saws to the smallest home owners saw. When I got fresh out of the navy and bought my property. I borrowed my friends 170 with a 16 inch bar. To remove some trees in my front yard to expose more view. About 16 or 17 trees!
All fell limbed and bucked into firewood. All Spruce. Any where from 8" D and 30' tall to 20" D and 80' tall. Well, after I wore out the factory 16" bar on about day two on tree number six or seven. I went to town and bought a 12" bar for it because I new the 16" was robbing power!
I finished all the trees in about 4 or 5 days. The saw and both the 16 and 12 inch were straight worn the heck out. Boy, I mean done!! I went through four or five chains. In that short week.
When I took the saw back to my friend he looked at me and said "where's my longer bar" I said "you don't need that thing It robs power" He said "I like it for reach!"
After he looked closeer at the saw. He said "Dude!! You owe me a new saw!!" I said "ok, I'll get you a 180. You need something with more power".
True story!
I ordered a 660 from Madsen's about a week later. For myself of course!
