i am unfortunate in that i dont live in osage country, but fortunate enough that i live in yew country!
i build all my bows from Yew!
self bows, board bows, and glass bows, i use yew cores ( the bland stuff) and prettier stuff under clear glass.
i have built ELB's ( glass) HH bows, R/D and recurve, even my 48" static tipped bow- all with yew exclusively.
it has never failed me yet!
It has its own challenges, its "moves" a lot, it is a tree that grows under incredible compression and tension forces, and can move after freshly sawn, so i always cut over size and trim.
but once in its final state- its stable and snappy!
