  We investigate the implications of spin symmetry for heavy quarkonia
production and decay. We first compare spin symmetry predictions for charmonia
and bottomonia radiative transitions with data and find they agree quite well.
We next use spin symmetry along with nonrelativistic QCD power counting to
determine the leading order alignment of P and D-wave orthoquarkonia that are
produced through gluon fragmentation. Finally, we discuss a mechanism which may
resolve the current factor of 30 discrepancy between theoretical predictions
and experimental measurements of prompt $\psi'$ production at the Tevatron.
This mechanism involves gluon fragmentation to a subleading Fock component in
the $\psi'$ wavefunction and yields 100\% transversely aligned $\psi'$'s to
lowest order. Observation of such a large alignment would provide strong
support for this resolution to the $\psi'$ problem.
