Best saw? One? That's tough, I've got best saws for their task for sure. My MS200t is absolutely the best saw I've ever used in a tree, what a ripping' little machine. One of my 028Supers is prolly my favorite, most picked up & used saw. My first Pro saw, bulletproof and just feels like it's an extension of my arm even at the end of a long day, most ergonomic Stihl ever produced (for me). For the big mutha stumps, big blocking, big wood my nod goes to the Husky 2100. Not that ergo, but can you say power.
So,... one overall "best", huh? That's gotta be my 036. My first new purchase pro saw and still running like newly broken in. My best "overall" saw I guess. Great felling, bucking and blocking saw. Good at limbing and can be used 50' up the stick if need be. Used to be my "big" saw before the 2100 fell into my lap, so I know she can do the big stuff when called upon.
Good thread, many interesting reads. I like to hear what others have to say 'bout their favorite saws. It's all good.
