AP Racing LMP231 SRR
Bit softer than HH pads but work really well with the cast disc
SR Offroad have them 01629-820111
They run both their race bikes on them and since Sam can show C.I. a clean pair of heels in a race I reckon what works for them will work for me.
Just remember to scrub down the disc to remove any trace of the old pads before you go out and try them.
I use one of those nylon pan scrubs and brake cleaner. Works fine and gives a nice clean surface to lay a film of the new pads on. It improves brake performance substantially, particularly when changing brand/type of pad.
Hope this helps.
