Based on the responses I am getting here: a strong favouring of 23, as 
well as my own preferences: I like some of the liveliness of 24 too, I 
will probably experiment with some interpolation such that, if

20.....23
.
.
21.....24

are vectors, then
X marks the likely settings:

20.....23
.....X
.
21.....24
