I appreciate the stability that Richlite offers. The neck of my Martin has proven the least problematic, and least maintenance intensive neck of any of the guitars I have owned, electrics included. Rarely touch the truss rod, and it's on a OOO sized acoustic with a longer scale neck. Go figure. In my experience Richlite appears to be a stable material, assists with tuning stability and it doesn't seem to be as sensitive to temperature variations and humidity fluctuations as Maple, Rosewood or even Ebony fingerboards. I think it's legit material and a functional alternative to the standard (and dwindling) organic fingerboard woods. I only speak with my experience with a single guitar (albeit an acoustic), but the material has merit and really shouldn't be dismissed.
