A lad that stopped at my house from wales had some on his toxin mod. Yeah, they were VERY loud, and had a VERY VERY good bite, BUt, they tended to slip faily often, i dont know if it was because the pads were just new, or if they always slip, but they were fairly good... These were in the CNC backings, which i cant afford im afraid So if they work just as good in the plastic power pad backings, they WILL be my next pads
