I've had some success on one D (on F21) by adding a small section of 
trichord felt, between the normally placed ones and offset by one string.

(v.v..) vs: (.v.v.)

No amount of squeezing the fat side of the trichord felt or even 
reversing one segment seemed to do the trick, and you practically have 
to look straight down on it to see a little red backing showing.
