Too much of this OAT and the top will simply crash to the ground. With a minimal amount, the "On-axis" torque will dominate and keep the top standing.
Are you talking about precession? I am having a hard time imagining wobbling that is not precession (unless the top is out of balance. Like a glob of mud on the rim of a disc like Carnavas said upthread...or an Epic)
