Nice looking pen. Like the finish you put on it. I'm still trying to get consistent with the CA. Sometimes I get lucky, but more often not.
I'll get there some day, but that Atlas looks good.
The one thing I was missing that fixed my CA consistency problems was accellerator. If you aren't using it, learn how. If you mess up, you can skew away bad spots and start over. Also, using high quality paper towels and wiping the medium back and forth a couple of times helps a lot. You can watch blobs and ripples disappear while it's still wet once the light's at the right angle. I also had to slow down and do each barrel separately instead of making just one pass. If any of this helps, cool. If you're already doing all of it, maybe post some specific questions about what's missing.
