That's funny, the 10mm is a great saw in stock form, but why the guys care if it's a 10mm or not once ported is beyond me as all the numbers are changed anyway, I'd rather have a late model 440 gilardoni on mine anyway.
Do you ever cut any previously dead standing ash, that's some hard stuff, that's what's being cut in the video I posted.
Here's a little perspective, same bar and chains, time the cut's, no real advantage to me with a 20" setup(yes a couple seconds I know maybe 15%, but the 361 is way lighter). Get up to a 24-28 and now my 440 will show the 361 up.
Now, put that chain on the 359, delete the base gasket and a muffler mod and lets see how far apart the crappy little farm ranch saw is
