I've never seen cores of zebrawood in a deep core longbow, and don't know how that wood would perform. It's kind of hard to draw a comparison in two very different limbs, recurve to deep core longbow. It would likely cost more for one, and part of the equation is density to reduce mass and potential hand shock, and good wood characteristics for performance when you shoot it. I'd say if you like zebrawood to keep it on the back and/or belly and use a known core wood. But, anything is possible. Looks like zebrawood is on the dense side of normal core woods, it would work of course, but I can't guess to how it would feel. I have a recurve with bocote cores, which is great. But only 2 laminations.
