i buy stones with a 00 angle and cut them for the job a 45 and a 30 may last longer the 60 is very steep and you realy should all ways use a bounce spring the makeup of the stone and how hard of a seat your cutting will wear the stone down i like the ruby red stones they are the old BD makeup and for a fine finsh the SX gp stones the stones should be dress every now and then the speed and the weight put on the grinder can add to the break down along with a very hard seat never force the grinder to do the job. if it is not cutting pick different stone make up you need to have a light touch with the stones or they can blow up and if you push to hard you can throw the seat off and have run off
