I don't have it (yet!) but if you search gardenweb for each name (cumaru and brazilian teak), there are several threads on here and on the kitchen board with pictures. Good luck!

Several years ago we installed clear grade Cumaru in an area inside a hotel lobby. It stained quite well and made a beautiful floor. I didn't take any pictures but you can see a bit of the floor here: http://www.pgaresort.com/photo-gallery Look under iBar. The first two pictures shows the Cumaru floor. With Cumaru, the biggest issue for many is the wide range of color. Did you look at the Sapele I recommended to you earlier?

its true that exotic species are a lil more finicky about temp swings. so thats where a good HVAC system comes into play. and i mean a good one. keeping the relative humidity at a constant. If you like the look of Cumaru then great, but dont get it because you think your dogs wont scratch it. they will. the finish will scratch, and you will see indentations from the dogs, if their active enough to where you worried about it, be prepared to see some flaws caused by them. they wont be gouging the floor but they will definitely mark it up.

Thanks for the advice. We currently don't have a home humidification system. We do run heat in the winter and a/c in the summer. We don't keep track of the humidity level in the house. I guess we should start checking that. The house currently has 60 year old white oak floors that we are having someone pull up and replace with new floors. The floors have very little to no gaping. The previous owners must of had pets because the floors has a lot of pet stains and also some larger water damage spots. Because of these issues the flooring company would have to repair much of the floor (probably 40% of the house) So we decide to replace the flooring in the entire house. The flooring company seems to know what they talking about but I am always the type of person to educate myself as much as possible to make sure its done right. We are buying the flooring and having the flooring company install it. We were not looking at the really cheap stuff at $1.99 a Sq ft stuff. What we were looking at is in the $5-7 range. Since the Brazilian Teak flooring seemed to be unstable I think we will pass on it. Our 2nd choice afyercthecteak flooring was a hard maple. Any advice on this type of flooring? The question I do have is about the moisture test. I understand that the flooring and subfloor must be tested and be within a compatible range. The problem we might have with testing the subfloor is the flooring guy is pulling up the hardwood and so it might be difficult to test until he pulls up the floor. If it's not capable we would have to reschedule the job and live with subfloor for who knows how long. Is is there any way to test some floor without pulling it all out?
