At this point I've come to the conclusion that I wouldn't trade any of the older 70cc saws like the 372 or 440 for a 441 or 576.

Andre.

Funny you should say that because the 372 X-Torq is back in my thinking for my upcoming 5 cube purchase (I wish Husky would have AutoTuned that one). I'm pairing it with a Snellerized 2153 (346NE) so I'm debating the weight vs the grunt, but the angry demeanor of that 441 is appealing as is the closer dealer support for me. If the 441 ported is as rowdy as billed, that is the way I'm leaning.
 
Andre if you need it another week that's fine with me. There's no hurry on my end.
 
Myself, Nik and Mike all had a chance to run the 576 and 441 a little bit on Saturday. Obviously both saws ran awesome, I still think I like the 441 more than the 576. However I'm slowly coming to the conclusion the 441's carb monitoring system may actually be less refined and more intrusive than the system on the 576. The 441 still seems to be fishing for proper tune, the 576 doesn't seem to have this issue, it simply feels like a more refined and smoother system. I'll probably have both saws for another week, so I hope to run them both a bit more before I return them to their own

Andre.
Too bad the muffler got opened on the 441 beffore it got broken in and before it was run with the 576 How does opening the mufflers effect the running of both of saws and does the mod cause some of these perceived quirks in the control systems? I don't know, but is the 441cm's system constantly checking and adjusting tune while the 576at's only check at first rev or cut and lock in parameters until the next start up? I have a feeling that the control systems on the two saws are very different in design and operation. I'm not saying one is better than the other, just differnt in how the systems work. I haven't run either of them yet, but for those that have does the 576at respond instantly with more grunt when leaned on like the 441cm is said to.
 
The 5 cubes are a good sized firewood saw. If they're warmed up a little they getter better.

I'm not sure what effect the MM had on the saw, but I doubt it's an issue. Like I said before a lot of this is subjective, but the 576 does seem to have smoother monitoring, does this matter much? not really.

I feel both the 441 and 576 are actually built better than the models they replace, however the weight and bulk of both saw is hard to overlook. Remember the 440 and 372 are only marginally larger/heavier than a 361. Some have said both saws are more efficient, they may very well be correct, but keep in mind fatigue reduces efficiency as well.

Just a few of my thoughts.

Andre.

that could be just a more conservative mapping/logrithm on the 576. The Stihl system may be tuning to finer increments. Just a thought also.

I'd say that both saws do have the grunt to pull 28" bars, but the oilers on both saws are at their limit IMHO. If you plan on running a 28" B&C most of the time, I'd say the 441cm and 576 would be a good choice, but so would just moving up to a 390xp. For an all around 70cc saw get a 372, 440, 7900.

I love the 576, period. I'm also uncertain which system is better but I can tell you I prefer the "real-time interaction" of the 441. I do understand how others may not. The best argument against it would be "who's gonna lead? you or I?." I see it a little differently though. To me, it seems like whatever I try to do, the 441 tells me instantly "ok, no problem, I can do that." I am however not a huge fan of the stiffer springs (the Husky's smoother) or the full wrap. All of this is just MHO.

My Stihls are/were miserly with the bar oil. The 460R oiler upgrade was the ticket for my 361, wonder if the 441 can be upgraded.

I'll use a 25" bar, and would get the R version for the upgraded oiler and other stuff. Might swap to a non-wrap bar, but then again may not. Like I said, I've got much better dealer support nearby in creamsickle flavor, so the 441 just may get the nod.
 
The 441 oiler can be changed out to a HO like the 460.

How many tanks through each of them now?
 
That sounds good Brad. It will be interesting to see how much the muffler mod gains.
