I used the Shimano resin pads (G01A, I think?) for awhile, then tried the TruckerCo pads, didn't notice any difference, so I started going cheaper and cheaper. I haven't noticed a performance difference (that is, stopping power) between any of them. There are pads out there four pairs for $20. The only pads I wouldn't buy again are Giants-- they were supremely quiet, but also supremely dusty, and they wore out in like 1,800 miles. Have used IceTech rotors exclusively.
