So there's a 36" Mill in the post & now I need to decide if I run it on a 385 or a 390... & when I get a 36" bar should I order full comp or skip chain, chisel or semi-chisel? The key thing here is that the 385 is ported, has a MM & stacks of compression. It runs noticably stronger than the stock 390 but I'm not sure if that makes it a better candidate for the ongoing stresses of milling... Any advice or suggestions appreciated
