Good advice to stay away from Bellawood Koa, I'm very familiar with that product.
RE: "Brazilian woods are no good". I disagree, sounds like someone has had some bad experiences. Brazilian woods can be great, depending on the Manuf. and the products in their line. And as long as their installed properly , acclimated, & the homeowner maintains the right site conditions, ( that's for any woods).
I think BR-111 has a great quality "Solid"Tigerwood ( Braz. Koa ), but I would stay away from their engineered products. A lot of installers dont like Armstrong, I happen to like them. They make a great Engineered Tigerwood in their Global Exotics line.
