I agree with sentiment Jim, but I wouldn't go so far as to say "the kind of wood has no bearing on the performance of the bow." Look at some of Bakers best performing bows (Pecan, Maple, Oak) while these are white woods and have different design requirements than say yew or osage, they all have mechanical properties that make them good bow woods.
You don't see great self bows made of alder, balsa, hemlock, pine, or lots of tropical hardwoods for a reason: their mechanical properties don't make them suited to the stress of being bent.
