Sounds like you have to much crank case pressure that is firing off that dipstick. Have you considered removing the spring and putting back in a stock spring to see if it resolves the issues. As I understand it, the spring doesn't change your scavenging only what you see on the gauge.
No - Taking off the D&D is enough of a job that I decided to not replace the spring. Although I do have a new HD "stock" spring for the SE cam plate and pump kit I put in (had to buy it since I can't find the one I took out).
FWIW, I removed a braided cable on the 05 cause it ate through the power coat from rubbing 
using a stock rubber hose now with ugly clamps. The wonderful Harley Chrome line increases the pressure in the crank area over the big ugly hose, it is a more narrow passage. It doesn't seem like much of a difference to the eye, but it is in diameter and flow.
Have you considered venting your heads to the ground instead of the intake or air filter / back plate if you are not doing so already?
I have thought about adding vents to the breather tubes, but I just don't think I will like the way it will look. Although it would be better then having the oil vapors dumping back into the intake.
I'm thinking the pressure is coming form the lower end. If it was going through the heads I think I would have more of a seepage/leak from around the mounting pedestal of the backing plate.
I have about the same oil seepage that I had before the cam, pump and spring. And it only started weeping after I added the chrome throttle body cover.
