The course markets itself as an inland links and there is enough sand in the soil to keep it open in the winter. But it's not enough to create springy links turf. The rough is wispy and the fairways are fast, but that is more a function of irrigation (or lack thereof) than of the type of grass. The sluggish greens are not fescue either, so overall the links pedigree of this course is heavily overstated.
There are a few interesting design elements, though. While the pebbly water hazards will probably not take the world by storm, some of the bunkering is quite creative. Normally the fairway hazards are placed for low handicappers, which means they are not in play for average hitters. Here it's different: the bunkers are often stacked or appear in several sets, so that everyone has to contend with some sort of trap. This makes the game more interesting for many players, who previously could just mindlessly hit driver and know that most likely they would never even reach trouble.
However, apart from that there is little variation in the design. The course is pancake flat and the industrial setting doesn't inspire either. Although there is a bit of ground game and the putter can be used a lot around the greens, the contours with one or two exceptions fail to entertain. Rosenhof is best enjoyed at a brisk pace.
