Now its popping hairs at tip and middle but not the heal. Guess its back to the lower grits again.
Hard to tell from the photo, but looks like you could move the corner of the heel forward and take the stabilizer out of play.
If you are riding on the stabilizer, it can keep the heel half of the edge off the stone.
Here is a photo from a recent post on correcting a heel. The red is the corrected arc and corner of the edge, compared to the green arrow, where the edge was currently ending, well into the stabilizer.
You can mark a new arc, with a coin and a sharpie.
