Prolly will run like a raped ape, but it looks like they have cut weight on the brake handle, cheapened it up. That's mine only concern, I love the performance of the 346 but the overall chassis seems a lot less robust than that of my stihls. One of the local loggers who use a 372 most of the time jokes he has as least a couple of sets of plastic onhand all the time for the breakage he suffers. When you don't gain weight with a strato design it has to come from somewhere. I hope the durability matches the potential performance. The 441 may be an ugly heavy duck but it's built like a tank, same with the old 660 design.
A durable stihl saw is the 038 and the 041, I see them all the time that are used as landing saws and have been used for 20 years full time!!!
