I've used LGMs,Belaeys and heatsink yellows. I'll start with the LGMs they were pretty amazing but they either need a good grind or need to be ran on a smooth rim, a dead/light grind won't do them any justice IMO. Belaeys really disappointed me, they were okay but I can't help thinking the chamfered ends are letting them down alot. They would be much better if there were normal and the bite and hold would definatley increase. Heatsink yellows are up there with the LGMs they are one of the best pads in terms of value and performance they are like £11 and they are savage on a grind, great noise bite and hold!
All in all I'd say LGMs or HS yellows. When my yellows run out I'm gonna try LGMs again
