With the MS 362, Stihl offers a 59cc saw, rated at 4.6bhp, with the power-head weighing in at 13 lbs. The mid-range MS 391 comes in at 64.1cc, 4.4bhp, and weighs in at 14.1 lbs., without the power-head. I'm going in to the dealer tomorrow to talk about both saws - the price difference is approximately $125 (20" 3/8 bar/chain combo). Most of the time, I need to run a 20" bar. There are a few trees (probably less than 10% of what I cut) that need a 24" or larger bar. I'm interested in a saw that can be maintained, rebuilt relatively easily, and can pull a 24" bar (even though it might be a little slower) on occasion. On the face of things, I'm a little surprised that the extra 5cc of displacement on the MS 391 doesn't translate into a bit more horsepower, but I realize there is a difference between the "pro" and "mid range" saw line. Based on evaluating the Stihl web site/literature, there doesn't appear to be a lot of difference between these saws other than the black handle on the MS 362 and the better spec. Before I talk to the dealer, a couple of questions: - does the MS 391 have a vertically split case like a "pro" saw? - has anyone used a 24" bar on the MS 391, and if so was the performance satisfactory? I'm OK with the price differential on the MS 362 if it translates into better long term performance and cost of ownership. I cut mostly cedar elm, poplar, a variety of oak, an bald cypress. Most of what I cut are diseased or damaged trees in clearing and reclamation projects, averaging two to three trees, including felling, limbing and bucking on a daily basis. The trees range in diameter from twelve inches to thirty inches or slightly larger in a few cases, particularly cypress and some of the older live oak. My employer provides a Stihl MS 230, running an 18" bar. It is underpowered, and under-length for most of the work I do. I have to re-hab saws of my own, a Stihl 011AVT, and a Husqvarna 142e that I use for limbing and trimming, as well as bucking some smaller wood. I'm ready to step up to a pro, or at least more appropriate saw as the current stable is inefficient, and in some cases inappropriate/dangerous for the work I have to do. This has increased in priority, as I'm now going to be cleaning up after significant flooding in the upper Guadalupe River basin after this week's flooding event. I decided to go bite the bullet tomorrow, and am leaning toward the MS 362, even with the higher cost.... I'd appreciate any guidance or wisdom from those who've used either saw. Stihl is better supported in my locale than Husqvarna, and Dolmar/Makita, Jonsred, and others are next to non-existent, so Stihl is probably the best choice relative to local parts/support.
