I did know what pads you were speaking about,I just cannot believe that you haven´t found one review in this 40pages long topic(I know there´s plenty of reviews of them)...But,I use them(tr brake,2bolt booster ,Sl rim),and they are good,not amazing,but my bro has them too(4finger hs-33,4bolt booster,urban rim) and his brake feels like from different world,superb bite and stupidly good hold too...
