You've really got a new 440 in the box?
That is really cool; one of Stihl's best ever. (I'm being serious now) I know plenty of guys who have done the same thing with 372's. (including me) Your 044 should last a good long while yet, but should she ever give it up, you'll be able to open up the box and have a new one. Problem is, when the time comes, you're going to hate to actually do it. Before you pop it's cherry, you'll have a look around for a 44 in nice shape to build.
Question for you and Tommy: When the 440 was discontinued, where did most of the business go, to the 441 or 460? I'd guess the 460. In my area, most of the 440 guys went right to the 460 without giving the 441 much of a look. Keep in mind with this 576/441 debate that Husky didn't have something like the 460 in the line up, so it was more important to them to find a way to keep the 372 around.
The 576 and 441 are both good saws, but very few people here would prefer them over the 372 and 440. Both of the new models have a little more power, but most users feel it's canceled out by the additional weight.
OK, back to the bickering.................You Stihl guys are all a bunch of (fill in feminine term of your choice)
