May aswell try Rim: Koxx try-all mod rim Brake: Maggy hs33 05 Grind, tar or smooth: Currently with a worn grind and a bit of tar but will re-grind if I am chosen Current pads: Koxx browns, not bad IMO but I am looking at trying a different pair of pads Booster: Rb 4 bolt I am average ability (40" sidehops, 7ft gaps etc.) but I heavily rely on my rear brake and can tell if its good or not. I can also set up my brake well I ride street and natural so I could tell you how the pads perform on each type of riding
