Thank you all for your help,

Heike informed me of some of these solution methods via email, and
helped clear up an issue with how mathematica seeds the streams for
the stream plot so as to make the plots syymetric.
Here is his solution for one of the systems:

AAA = {Cos[1 Arg[x + I y] + 0], Sin[1 Arg[x + I y] + 0]}
points = Table[0.5 {Cos[th], Sin[th]}, {th, 0, 2 Pi, Pi/6}];

StreamPlot[AAA, {x, -1, 1}, {y, -1, 1}, StreamPoints -> points,
 StreamScale -> None]

Best,

Mike
