I was given a set of sintered 3/4 used front pads for my 00 kato 250 at a race which was unusually hard on pads ( a set a lap for the fast guys). this was in about 2006...the bike still has them in the front. feel is down but they just don't wear out. you can grab a big handful in a full panic and not go hurling over the bars. I find them ok to use just took some getting used to... I would get a set of each and use the sintered on long rides that looks muddy and sandy.
