Also called Kwila or something like that. I made a 66in 45# er at 28 in out of board of this stuff. Basic pyramid design with trapped back. Shot great but after a couple hundred shots it raised a splinter on back. Could have been a tillering error, the wood might be a little brash or i could have been a inherent flaw in the board who knows. You might consider a hickory or bamboo backing.
