Just for clarification the wood was super soft Bass wood, about 24" or so. My 7900 has only had about 5 tanks of fuel through it and it's still very tight.
Pros...
From just feel, the 441 acts like it has more than one gear, when you really push down on her it just keeps going. IMHO this is solely because the saw can compensate for the load and add more fuel when needed. The 441 definitely has plenty of power, a stock 460 would struggle to keep up in any size or type of wood. On odd thing about this 441 is the fact the engine doesn't feel very tight, I can't say how much it will pick up with more time on it. Don't let the numbers fool you this saw pulls harder under load than the 7900, yup I said it. Despite the numbers I think it has a more usable power band than the 7900, not by much, but it's there.
The AV is fine but not as smooth as a non wrap 441, or the 7900. Keep in mind I have always thought the 441 to be a bit smoother than the 7900, not so with the stiffer springs, but still very smooth, much more so than older Stihls, it's a non issue. The saw started in two pulls after sitting all night, very cool.
A few Cons.
I did a bit of cutting in really thick woods with lots of undergrowth, and I can't say it's the best saw in this environment, especially with a 28" bar. Again the power is there, but so is the bulk. In my hands it reminds me more of a 390 Husky than a 372, it's a very bulky saw for the displacement. When I was swapping bars I handed my brother each saw without the B&C and asked him what he thought, he guessed the 441 was about 14.5 pounds. I handed him the 7900 and he quickly guessed it was 2 pounds lighter, this is obviously subjective, but I think he's close.
I do see a potential design issue with the 441. The integrated control lever has a lot of play, and when you push it all the way down for cold starts the lever bends and moves the carb around too much and doesn't always close the choke fully. I've never liked the master control on Stihl's, but this one is the worst operating out of any Stihl saws I've used.
So would I buy the 441M over a 440 or 372? That would be tough, I just don't know if the power makes up for the bulk.
