Any experiences or comparisons with the current PROMICROL developer, liquid version?

I´m interested if anybody uses the liquid Promicrol, that should still be produced in England and can also be bought here in Germany. Especially I would like to know, how good it is in comparison to standards like ID-11 / D-76 or Xtol in terms of sharpness, grain and exploiting of film speed.

Thank you in advance,
Andreas
