Brake pads for 2013 Road King / sinter or organic version???

Since I renew the DOT4 brake fluid this week, I also wanted to replace all brake pads. Can I assume that organic brake pads were installed from the factory? I was very satisfied with the previous ABS brake performances. With the TRW/LUCAS sinter brake pads (781), it is explicitly pointed out that they should only be used if sinter versions were installed before? What would be, besides the high-priced HD material, still renowned brake lining manufacturers, b Zw. where would be a good source for organic coverings in stamina quality. Have no desire for any experiments with low-budget manufacturers! Gruss Nico
