In general: on loose and light soils solid rollers carry better than open rollers. In addition, solid rollers tend to suffer from less blockages. Exactly for this reason on the wedge ring and Matrix wedge ring rollers, the rubber rings are fitted to a solid tube. When the rings sink into the loose soil, the tube carries the weight across the entire length. The sticking of any dirt, capping or blockages is not an issue!
