I made my girlfriend a burlap backed red oak bow for Christmas (my first bow). It shot pretty good, about 30 pounds at 26 inches but she let her dad shoot hit who drew it full draw (around 30 inches) twice and then it broke. I am now going to make a hickory backed bow maybe with ipe for a belly wood (suggestions welcome) and I am just wondering, in general, how much more durability can I expect out of a hickory backed bow vs a fabric backed red oak. Thanks
