I feel like Ace bushings are like a very linear steering damper. They are happy to support you in whichever direction you want to go, straight, left or right. Very steady, predictable and confidence inspiring, but they don't provide any rebound or bottom out resistance. However, wheelbite is soooo gentle, it's more like wheellick.
Indys don't want to go straight, they just want you to pick left or right. The orange bushings provide a small bit of feeling and responsiveness during most of their arc and only minimal push back towards the end. The blue bushings are kinda feelingless towards the middle of the arc, and are more like hard bump stops towards the end of the travel. I could ride these with the top washer rattling loose, but still not get wheelbite.
Thunders want to stay centered but will let you turn. Their bushings are extremely progressive. A little adjustment to the kingpin nut makes a huge difference
