For you builders who build mainly in all koa. My question is about using koa as your top wood opposed to say spruce. Certainly its partly asthetics? Its partly tradition? Maybe even what your clients want you to use? But what to you are the benifits musically? Whats gained/and if anything whats lost. Sorry if this has been hashed out allready. But I couldnt find this in the search, then again I can barely type. Thanks to all.
