Standard AE pads are $6-$7. So for two and a half times the price you get something that may never need replacing for as long as you have the buggy? That plus the constancy is worth it to me. They don't fade even on a high bite track where they are working hard. The only reason I have to adjust them is if the track conditions change and I want more or less slip. I almost bought the avid slipper but didn't see any advantage over the stock setup with Garodisks.
