I'll have to get some to try out. But still in comparing the 8" to say a 17" pad you have to remember the whole pad is not used. Three 8" pads are really not that much less surface area compared to the area that actually makes contact on the larger 17"-21" pads....where the center and outer edges are not used.... Only where the bristles on the driver actually remove dirt. I can tell by the stains on my pads
