mooman...you sure you meant Bubinga & Ovangkol to be the same wood?

Ovangkol is usually Guibourtia ehie and also called Shedua or Amazaque.

Bubinga is usually listed as the name for Guibourtia Demeusei or a couple others. They certainly are related species which MAY sometimes be called similar names by the tribes near where they grow, and this demonstrates my point that common names 'can' be tricky.
