The redish colored cups are the Cocobolo. I decided to go with a slightly higher angled wall with the Coco's versus the shorter angled wall of the Blackwoods. Both turned out very nice. Antique oil, then buffed with the Beall Wood Buffing System which I finally broke down and bought, with a final coat of Carnuba Wax. Silky smooth, semi-gloss, flawless finish.
