George...that's funny.
Good topic. I've spent a good deal of time thinking about this as well.
I've spent some time outdoors living in a primitive way and I can tell you that after a while, you just get used to the idea that everything you do is going to require a lot of effort: (e.g., in the rain, with tools that get dull real quick, when it's windy, with fleas biting your private areas, listening to your stomach growl, keeping the fire going, and with your dependents (dog, children, wife, in-laws, etc) putting the screws to your brain and wishing you could hurry up with your funny looking sticks and bring home the venison.....)
Seriously, as far the the "feel" and "weight" thing, yes, that's part of it. So is the smell, color, toxicity, straightness, etc. If you've ever had to gather lots of firewood over a long period of time, you get to know your wood pretty good: how well it cuts, splits, breaks, dries out, responds to coppicing, etc. Using this knowledge, it's easy to select bow wood.
The actual experience I have working with primitive tools and living in a primitive way (by myself....thank goodness) has revealed that in order to make anything of lasting value, you've got to do a lot of tedious, back aching, finger cramping, callous creating, repetitious movements. But you tend to forget the pain if the wood is a pleasure to work with. The way it looks and performs in its final state is also critical....maybe even more so than it's workability. I think primitive man spent a lot of time choosing materials based on
many more aspects than we do in modern times.
