Nice post and pics. I've pretty much given up on those saws, and even the heavier "chain saw" type. I agree... you can make them work with proper technique and a bow. But I have just stuck to whatever size wood I can saw with the saw on my multitool or SAK, which are EDC for me in the woods. In my pack and in my camp I use a Fiskars sliding saw, which I love (particularly the belt clip).
