I think the reason most folks use the flooring for lams is that they can't get bamboo in a good form for resawing into lam blanks. The flooring in this case the flooring is a lot easier to process than raw bamboo, and it works well. I bought a whole box and have used it quite a bit now. However, if I wanted another wood, I would prefer to get it in planks. I've done that with yew, walnut, locust, hickory, maple, cherry and osage. It's a lot more fun to start from a plank, cut out your billets and resaw your lam pieces from that and then grind them down to your specs. With flooring, you generally have to buy a box of it, which is pretty expensive and you end up with an awful lot of that one wood. Unless you're going to be making a lot of bows, it's more fun to go to a hardwood yard and pick you own woods. When I want to build, I like to go down to the shop and look things over and decide what woods I want to use this time. I generally only use the boo for cores, though I've also made cores from all of the woods above.
