When I started building a few years ago, lots of the people I talked with were using the vertical flooring, which they called lamboo, and liked it, so I did, too. I also like it. It's easy to obtain, very consistent and a pleasure to work with. You buy a box of it and you have a lot of bowwood on the shelf. It seems to give good performance. Absolute state of the art top performance? I wouldn't know, I don't work at that level. Will it last 50 years? I don't know and won't be around to find out.
Subsequently, I started hearing about Actionboo, which I think is manufactured specifically for bows. I have no experience with it and I'd really like to see someone very specifically explain the differences in structure and performance. I think a lot of us would. I think there is a lot of cross use of the terms and clarification would help.
I use the lamboo as core under veneers or figured lams. I don't imagine the performance would differ under clear glass, but I don't think I could handle the appearance. It would just look strange to me.
I might also note that other woods, yew, osage, maple give excellent performance as cores, but buying the wood is a bit dicier as you often have grain areas that aren't aren't usable. I've recently built a couple of bows of clear walnut that kind of knocked my socks off. For me, the beauty of the lamboo is its consistency and easiness to work with.
I'll be watching and hope that someone with some in depth knowledge of lamboo/actionboo comparison chimes in.
