I have made a few flatbows out of hikory and ipe but I have been taken by a cheap bamboo/ osage elb that I bought at the Texas Longbow shoot a few years back. It shoots better than any of my flatbows and I am now wanting to build my own. I plan to draw 50 at 28, 69 to 72 inches long, and want to back it with either bamboo or hickory or linen, and have a core of either hickory, osage, ipe or ash, which ever is better. I do plan to hunt with it and want to know which combo of backing and core wood would perform the best for a narrow profiled elb with the least amount of handshock. Any suggestions recommended. Thanks Bhill
