hahahah! OK, I admit I got CAD after joining here. hahaha! But the necessity of getting a larger saw at the time was obvious, and glad I did. I think if you are going to be cutting all the time forever for firewood, and taking whole trees and scrounging, which means you will be seeing from one inch to three foot or larger diameter, you need at least a three saw plan, small medium and large, large being 70 cc or larger. If you live someplace where you know real large trees are non existent, fine, a coupla smallish saws. Now people in areas with larger trees can and do get by with smaller saws, but you never know when an emergency can happen where a big saw is the ticket. You just never know, big trees come down all the time, usually when you aren't expecting it, but have to deal with it.
