It depends on where you ride. Here in N Florida, our soil is very sandy. Even our hard pack single track has a layer of sand on it. The drive train is constantly bathed in sand. Where I ride in the N Georgia mountains, it's relatively clean with a little water and mud once in a while. White Lightening is the best choice for N Florida and it works very well. In N Georgia, you'd have a lot more suitable choices and probably should go with something better suited to moisture protection.
