I use a 16" Stihl bar and chain with the .043 kerf on my MS200T. The Stihl dealer tells me it is not recommended for the 200, only for the 192, but it sure cuts a lot faster than the .050 bar and chain. It is also lighter.
Dont you have a problem with bending the bars?
.043 kerf ? How do you sharpen? Does the wind deflect that bar much?
