The tree on the house guy has probably never seen a wedge in his life. Like many guys around here if you put a face in it the tree has to fall in that direction no matter what right? wrong. His saw could use a tune up too. Old lady commentary is great, wish I could see the fallers face when he turns around!
Longer bars have saved my ass on several occasions and they will again. Bucking under pressure for one. Felling a hazard tree you are already that much farther away,2. Extra reach limbing, walking a log or not, 3. Back saver,4. Most of my terrain here is flat. We do have plenty of rolling hills and steep drop offs but nothing like out west or in appalachia. I can get most of my work done with a 25" and that is the shortest I have run for about 5 years now. Bigger or hazard trees or more dangerous bucking and I've got a 36" bar for those. Originally I ran 16s, 18s, and 20s for the first two years of felling because that is what the boss had. I had a revelation one day after getting poked in the eye about a hundred times by sticks that a longer bar will give me longer reach and safer distance. I put a 25" bar on the bosses acount and never looked back. I run 25" bars on my 60cc saws and 28" on my bigger saws 70- 80+cc, but I also have the 36" option when I need it. An extra 5" may not seem like much compared to a 20" bar but it really is an extra step or so away. It seems a lot farther. Just like a 32" to 36", only 4 inches but seems like a mile. Around here a 32" does not seem practical on a daily basis, but 25" and 28" do for sure. Only three cuts on a tree instead of 6 with a smaller bar is a lot easier. Also if you can only cut from one side of the tree and the bar is too short, its not a lot of fun. Short bars have their place, just not for me.
