I'm new to the bowyers trade, but long on woodworking experience. This vrtical grain bamboo flooring is excellent material! i just worked with a bunch of it this week and have lams milled for several bows right now....light weight, strong, flexible, with good snap to it, or memory....i'm thinking this stuff would make an excellent board bow with no fiberglass at all....i'll be trying that one when i run outy of glass i'm sure.....
Riser wood???? No problems i see at all...the factory laminations are excellent.... Kirk
