You actually have excellent first hand data to add, and u have not personally experienced failures at this point. The ones you "know" about are second hand again just hear say, even if they are your "friends". And we both have opinions, I will post mine as I have my hands on different saws. You went to the Stihl narrative as that is your preferred saw which is all good and part of your experience. I can post a video on my experience if you want. I have a shop with a pile of cases. 461's and early 372's. You stated your opinion. Mine is a little different. Both manufactures have saws with nylon caged bearings that last a normal service life. After tweaking the 372 XT, even those last a normal period of time. I have seen and taken apart several 461's and 372's after a "normal" life that quit because the nylon crumbled and the bearing failed, I see them as successful saws as they earned their keep for the owners. As I see the "hands on" events, I often report with a video; but ONLY on what I have right in front of me. Here is one such event, actually one of a few with these saws. U have anything hands on you can report? And the answer is "yes" , you have both 462 and 572 that are working and to this point have not failed. THAT is first hand and excellent data. As mine is. The NEXT level is "opinion" and interpretations of other folks events, second hand data. That is where things get muddy. I too have a failed 572 case but I know how that happened and it wasn't stock therefor really not of value.
Just curious what was Husqvarna's idea behind going with a 39mm stroke?
