In the case of Metol the middle ground, as in most practical is D23. But the there are good reasons it's not used by many.

Having long been addicted to replenished D23, I tried D25 several times but it was just too soft, and mushy for my taste. Kodak does suggest using half the bisulphite; but I never tried it. D25's replenisher, DK-25R, however, is what I use to replenish my D23.
