Very similar collimating agents have been proposed for outflows from both Young Stellar Objects and Planetary Nebulae. In one proposal a spherically symmetric fast magnetized wind interacts with an environment which may include a strong pole to equator density stratification. This leads to wind collimation through field amplification in the post shock region. In a second proposal, the wind is smoothly collimated via tension forces. We present studies of the interaction of these two forms of magnetized winds with aspherical ambient density distributions in order explicate the dynamics of resulting outflows.
