Yes, Padauk is hard. When compound cutting, I use Pegas #6 or #7 Skip blades. The MGT blades have reverse teeth which can clog the kerf. the #5R MGT blades have 11.3 tpi and the #6 Skip blade has 12.0 tpi. You are not far from Dayton, so you might stop by the store and check out the Pegas Scroll Saw.
One thing about the Padauk is the dust. It gets all over everything. Also I noticed it darkens with age.
