Though my wood shaft knowledge is lacking compared to many here , what Steve Clandinin says makes a lot of sense with the Hickory shafts . Hickery is TOUGH as is, and in these parts AVAILIABLE which is crucial in a survival situation on a long term (indefinite) situation .
Lots of arrow options in these parts..River Cane -dogwood-hickory -maple-even Osage could be another , though getting enough for straight sharts could be testing to say the least...
For a survival Bow wood ...in these parts...Osage-Hickory again shine if I can't take my Montana Longbow ...Fun thread ;^)
