yeah widrose can be pretty knarly.
It takes me some long hikes (Christmas morning is my favorite for foraging long treks)
to find the straightest and the toughest. the ones i've had most success with are oversized 1/2" at the base and red brown to grey bark.
ones that are less can end up under-spined and they seem to shrink too much.
One of my faults has been to reduce EVERY shoot I find to 11/32 as if its a magic number...
and i'm FINALLY realizing not only does it risk weaker spine
its just not completely necessary. so... i'm planning larger dia. on this past years batch of wild rose and see if it helps.
I've gotten myself so conditioned to 11/32 shafts i can almost eyeball it...so this'll take some getting used to.
