  We modelled the radio and gamma-ray light curves of millisecond pulsars using
outer gap, two-pole caustic, low-altitude slot gap, and pair-starved polar cap
geometric models, combined with a semi-empirical conal radio model. We find
that no model fits all cases, with the outer gap and two-pole caustic models
providing best fits for comparable numbers of millisecond pulsar light curves.
We find a broad distribution of best-fit inclination angles as well as a
clustering at large observer angles. The outer gap model furthermore seems to
require relatively larger inclination angles, while the two-pole caustic model
hints at an inverse trend between inclination angle and pulsar spin-down
luminosity.
