We present high resolution H-alpha long-slit rotation curves for a sample of high-mass galaxies. These well-resolved long-slit data will serve to probe the interior shape of rotation curves and therefore put constraints on maximum-disk velocities. This is crucial for accurately modeling both the luminous and dark velocity components. Ultimately, this data will be combined with optical and near-IR photometry to determine the most accurate possible mass maps of disk galaxies.
