First off, congratulations! That beastie looks sharp, and I bet it sounds even better than it looks.
I have a favor to ask: as you spend some time with the Decade, could you please let us know a bit about how it balances while seated/standing, and whether the short lower horn fits comfortably on your leg?
I'm really interested in a Decade, but I (and I suspect other TB members) have never seen one, let alone spent time playing one. It's got such a unique shape that it's hard to tell whether or not it'd be comfortable and balanced without having the bass in hand. Most of what I've been able to read about the Decade on TB.com concerns the sound of the Darkstars or Chi-Sonics, rather than ergonomics/playability.
Again, congratulations, and I hope you play it in good health for many years.
