My first bamboo backed bow used Jatoba on the belly. It's R/D, 70" N2N and 61# @ 31". The boo is a little more than 1/8" thick and the Jatoba is a little more then 1/4". made it 1 and 3/8" wid at the fades with a straight taper to 7/16" nocks.
I used resorcinol for the adhesive. I scrubbed the oils out with dish soap and rubbing alcohol before glueing.
I chose Jatoba because it was easy to get and because of the physical properties. If I read the charts right, it has the density of oak, the compressive strength of osage, and a higher MOE than osage. Plus, it's just really pretty!
Good Luck,
Brett
