Well just to update incase any one else searches
Banged in a new pair of uber bike semi metallic / organic and low and behold absolute silence!
Also feel a million times better braking wise than SS sintered!
Dunno whether SS sintered suddenly have a dodgy batch but I couldn’t get them stop squealing at all, I’ve used them for years and no noise in he dry or wet then suddenly the last two pairs the same noise
Anyways I’ve properly bed these in for the first time in ages on organic and the bite is great, really solid grippy braking and silenceeeeeeeeeeeeee
Not bothered it they squeal in wet weathers I’m sure once I’ve got them hot again they will be quiet like normal, and at 18 quid for four sets even if they get half the wear over sintered I can live with that given the silence
So organics for the win for me
