I'm not a logger, cutting down trees scares me. I salvage what is on the ground unless the smaller tree to cut down is in a wide open area. I'll avoid any trees that would bury more than my 20" bar.
Max width when milling will probably be about 26". In my area there are very few trees that will be available at that size. If the saw struggles with a sharp chain I'll get some skip tooth chains.
A bigger bar would require a bigger saw, material moving equipment, a bigger truck, a trailer set up for log loading / hauling, etc. I'm not equipped to move big stuff, have no storage for the equipment, the waste, or the wood. That would quickly get to be overwhelming. I'll keep it small and enjoy the hobby without making it a job.
