I too agree with these guys.
If I may add, in order to minimize the crushing effect of the boo on the oak, make sure you get the bamboo as thin as possible, wring out every available inch of working limb, make every inch do its part from dips to tips, keep the stiff handle section relatively short, and you could utilize a trapezoid cross section to help also...I.e. narrow the boo on the back while leaving the oak on the belly wider.
