My own experience with Sure Starts is they don't hold settings; they slip. Not a lot of experience, but what I had was not good. Like the TA, they default towards rich. So maybe that's your richness?
Now in thinking about it, I wonder if I'm right re the way Sure Starts are sprung, and what the relaxed position is. I don't have on handy to look at.
