I don't know about you guys, but this is the most dense wood I deal with. Cherry is easy to saw through...but those 20+ inch oak logs are so heavy and dense that I have to rock my saw back and forth a little bit and that's only with a 16" bar. This is where the 440 would come in handy. If I go in hard with the whole bar buried, it basically slows my chain to a crawl or complete stop.
