I'm looking at getting another chain saw. I have a Stihl 056 (32 inch bar) and a Stihl 018 (12 inch bar) and I need something in between. I've had very good luck with Stihl equipment and have been looking at a Stihl MS029 (farmboss). The Stihl catalog says the recommended bar length for this saw is 16 inches; my dealer has them with 20 inch bars and has said the saw is balanced for a 20 inch bar. He'll knock $10 off for the 16 inch bar. I live in timber country (Idaho panhandle) so I assume the dealer knows what he is talking about. Is the catalog right? or is the dealer just trying to sell longer bars (I can't understand why he'd do that)? Anyone using one of these saws? what length bar?
