One of the most promising avenues for determining the distribution of mass in the outer parts of early-type galaxies is through the kinematics of planetary nebulae (PNe). We have used new techniques and instrumentation on the WHT and the VLT to obtain velocities for hundreds of PNe around several nearby galaxies. We show simple mass models and describe more rigorous orbit modeling methods for the combined analysis of different dynamical constraints in galaxy halos.
