I'm 6'4, but my brawn is transitioning to something else at my age. Years ago, I was built like a freight train. Now, I can hold my own, but I don't work out any more, and have a bit of a gut. I need to fix dat. Gotta at least keep up the image.
I have never seen a need for a compression release on anything up to an 066, but the old 051s, 070s, 090s, etc. really needed some help.
I have cut a lot of wood with an 041, and that sound brings back memories. Even so, while it's nice to make a few cuts with an oldie, I prefer my MS440 for actual work. Best saw I have ever owned.
Back in the day at Vail, they came across a 14 foot diameter Sitka spruce that had to go to the mill. They cut the tip off of one 16" roller nose bar, and the tail off another, welded both bars together end to end, and wrapped a bunch of chain around it to fall that monster. Used an 090G. Loaded it with the tower on to off-highway trucks, and away it went. I didn't see the tree, but I sure wish my dad had taken some pics.
