I have done English longbows, stiff handled American flat bows, and bendy handle Native American style bows from mulberry.
I have cussed a blue streak chasing growthrings around pin knot clusters until I needed an inhaler to rescue me from a death by asthma. But I learned to follow a growthring like it was a religion and to respect the grain of the wood with mulberry.
Anyone turning this opportunity down is a fool.
