Let me know how you like those pads. Right now, I have some cheap drilled slotted rotors and unknown pads (from po). I've been driving on them for a few years, low dust, but the bite is nonexistent. And they squeak like crazy once warmed up. I'm waiting for them to be used up to replace, but they are still at about 50%. I might just swap them out because they are really getting annoying. I've never had much luck with aftermarket pads. They either squeak or don't have enough stopping power (or both). OEM is pretty dusty but I love the bite.
