That's what I have in my stable. A 55cc and a 72cc. Both Stihls.Definitely skip the 460, the Echo CS-590 is superior in every way possible.
That said a good 50cc and 70cc saw combination is where it's at, if you have the $$
A couple of years ago I got a Husqvarna 450. Didn't use it until a little bit this year. We decided we were going to burn wood alot more so I bought some tree length. Well I ended getting a jonsered 2149 given to me which is essentially the the same saw. So I sold the 450 to my son in law. And he gave me 210 as a trade. So I have two saws.
My dilemma is I got 8 acres that are a mess from ice storms and a friend wants me to clean up at his 10 acre wood lot. So I got alot of wood cutting in my future. I don't think my 2 saws are enough. So I was thinking of getting a 545 or a 555. My friend friend swears by his xp. But he's a pro . And I'm not a huge fan of the silver. I just need some help. Looks like I'll be cutting 20 plus cord for next winter and I want a good saw. And I don't want to wear out my jonsered.
I haven't pulled the trigger yet. I just want to get one saw that will do most. If it takes a little longer no big deal. I change my mind daily. I am looking at that saw. I shrink my list then it grows again. But the research is alot of fun for me. I'm gonna have my jonsered and whatever I get so I should be goodA few yrs ago I was in the same boat as you. Needed a bigger saw but did not know what to get. I shopped Husky, Stihl, Jonsered, and Sachs-Dolmar. In the end I went with the Husky 365XT because I felt it gave me the most saw for the money. And as was said earlier, it can be turned into a 372 with little effort as it is essentially the same saw. I have had it for going on 8 yrs now and have even done some pro work with it for a logger neighbor of mine who ran short on help one summer. Spent 3 wks working for him running it about nonstop in all hardwoods, ash, cherry, oak, and maple. Only thing I have ever done to it is replace the pull starter as a couple teeth were getting worn and sometimes it would skip and jerk when you pulled it. Very pleased with it so far.
