I don't doubt that a stock 200T used primarily for pruning and an occasional removal, would last for many good years.
But I pretty much specialized in big strategic removals 6 days a week.
Never got much more than two years before my mufflers rattled off, and no amount of new Belleville conical lockwasher's could ever solve the problem.
I hope and believe that Stihl is perfectly capable of designing n building a bullet proof gas powered trim/removal top handled saw.
They could even go retro and build one with dual triggers like my old Homelite Super 2's.
