25 phbl

are the „D“ range of needles available, rated in that the higher the number, then the leaner the needle eg; D22 rich and D36 is leaner

funny enough, i found it on LCGB forum last night , cheers anyway

i have a list of needles somewhere from mb developments that run from weakest to richest and they dont follow any sort of pattern. mail me direct and i will scan it and mail it to you.
