I did a quick dogpile search for wood strength, and this link came up.

It seems to indicate that there is more than a 20 % difference in strength properties from WRC to oak, but it may note matter for your project - I don't know. The WRC I used was Western Canadian old growth, which might be different in how it behaves to your wood.
WRC can grow to amazing heights - which means it is really good at transporting water (and dirt) up the trunk. The particles are small, so I don't think you can see them with the eye, but the stuff is just heck on blades - sort of like carving cardboard and paper.
What I can tell you, is that it just destroyed normal steel router bits, and it wore out more than an expected number of carbide ones - but - it was my first project with a router (hand held) and I was still very much learning how to use it.
I think of WRC as a construction / fence / outdoor use wood, not a furniture oriented wood.
Make sure to use stainless steel fasteners. The very nice tanin that protects the wood from insects, also makes even galvenized fasteners rust. Guess how I know.
