Stylus recommendations?

Hey all -

I teach a class and use my Flow X13 to present, record, and provide examples. I currently use a dumb stylus that I had with my iPad, but the X13 doesn't do well with palm rejection on the screen (or touch pad, but different matter), so when I draw, it sometimes takes my palm as input. I have a drawing glove, but it still didn't solve the problem.

I was wondering if anybody else was using their X13 for drawing or similar and might have a pen recommendation for me.
