dmnc,

FYI - you can get GT85 from Halfords (probably in the bicycle section).

I have just got the AJ 'tri-hone' pack, and am currently flattening them - the '12k' LM is certainly harder than the '8k DT' and the '15k LM', and my well worn 325 'grit' DMT8C is having a bit of a time of it !

I have got a 220/325 'grit' Duosharp plate coming, so that should speed things up

Have fun

Best regards

Russ
