Dude, have you been reading my emails?! I'm also chatting with Marc at the moment about a short scale OM with very similar specs, but I'm on the fence about letting my beloved SJ go. I'll be watching this with great interest! I originally thought of doing Adirondack/Mahogany for mine but have also been looking closely at the torrefied Sitka. I love Marc's standard Sitka paired with the Padouk on my SJ and agree with your thoughts on it's benefits when paired with a resonant back and sides.
Way cool
