Okay, admittedly, I was being a wuss with those first two horrible doodles. I had been holding the pen awkward and keeping my hand up off the tablet. I was treating it too gently.
So this time I dove in and rested my hand on the tablet (It doesn't pick up the presence of my hand, which rocks!) and held the pen comfortably and just went for it.
Oh yeah, I can do this.
This is awesome. Just wish I had ArtRage5, lol. But OpenCavas will work for the time being.
