Design of the bow definately has the greatest impact on how a bow will shoot. That said, I strongly believe that the woods used in a bow, especially a longbow, make a difference in its characteristics. Red Elm, Canarywood, Zebrawood, Maple, Bamboo, Yew, Black Walnut, and others all make for good shooting bows. They are all durable and have good recovery speeds. It has been my experience that when I use Bamboo or Yew that I have to add to the overall limb thickness to hit the desired draw weight. Osage, Black Locust, Bubinga and some others are also excellent woods but seem to have a little more handshock. That's not a big deal on a recurve but I believe can definately be felt on a longbow due to the number of lams in a longbow. I prefer to use them as the center lams on a longbow in combination with some smoother shooting woods. The other option is grinding them down to .020 or less and using them as veneers over another corewood. This allows them to show thru the glass and at the same time reduce their impact.
