Just thought I'd throw the question out here. Most dark woods are dense, right? Are there any less dense options? Criteria: 1) less dense than black walnut (41 lbs/ft3) 2) available 6/4 and thicker 3) not impossible to find 4) dark -- mahogany/sapele is not dark enough Peruvian walnut would be great, but no one cuts thicker than 4/4. Post sources if you've got them.
