Perhaps a bit OT, but if you can't put a pint or whatever atop your rig without it doing St. Vitus dance it indicates insufficient bracing of the cab. Aside from the issues of where to put your drink any energy expended in vibrating cabinet walls is energy not making it's way to the audience as sound. The two corners most often cut by cab manufacturers are bracing and damping, as you can't see if they're properly in the cab without opening it up.
Tilt backs are a good idea in a combo, as combos should be tilted back so you can hear the mids. The reason for a dearth of them is the same reason why most acoustically valid concepts see limited usage, and that would be how it looks.[/quote]
I recall I couldn't leave anything like a tuner or my watch on top of my old Ashdown rig without it falling off after a while, but having a cab braced up to its eyeballs won't stop people from stumbling into things.
