Dear Graybeard:
Truth is, most times I looked for a dead branch when I entered the woods. Still do, mostly because the opportunity happens without any planning. I prop the thing up near where I park the truck when I'm done, so I can use it next time. Usually find it when I return.
Pretty comfortable to have on a little hike, and certainly makes for steadier shootin.
Most of the ones that I've...improved on.. have been chosen because they just caught my eye, with no regard for species. A little cord and varnish, some construction adhesive and tubing for the tip,
first class all the way.
Bamboo? Yup!! One of these days I'll find hunk of Boo that looks right. Hickory, Maple, Locust, all good stuff, all sensible choices. But Sumac! I never would have considered it. I guess that I'm really surprised at how well it worked. Woodbutcher
