We all lean towards the koa because that's what Hawaii is known for. But it's tough to work with, especially when you get the curly koa. Because of the complexity of the grain, it's a very challenging wood. Mango is a fabulous wood and it's underrated. For some reason, it doesn't carry the influence that koa does. Mango is some beautiful wood. I work some 30 varieties, generally, because I love the variety.
