These things helped me:

Learning to strop evenly with the spine on the strop the whole time. This is a big one and I didn't notice I was doing it wrong until about a week ago (I am 8 weeks into straights). I downloaded some audio files of what stropping SHOULD sound like and I was doing it completely wrong.

Lather is different with straights, weird huh? Straight like a thinner slicker lather than my DEs do, where they lick thick fluffy lather.

Angle: I found I was using too steep of an angle on my face and now that I've lowered it and cut down to SUPER NON EXISTENT pressure things got better. with ATG I use the blade so flat angled that the spine is touching me.

Prep: I shower before I shave, AND use the hot towel method after I get out of the shower. I use a steaming hot towel . this really helped.
