Here are two ways to drive them for a Heelside approach if you are regular footed. The right drawing is probably more popular but both will work and you can use either depedning on lake area in turn around. The one on the left is the easiest to drive, but usually requires a quick turn after hitting the roller to return the original wake path which some people do not like.
In the right drawing after making the turn at point 1, be sure to drive straight and probably need about 100 or more yards of straight driving to set up the rollers. Can also slow down a little at around point 2 if you want bigger rollers and DUps but this is not necessary. When you make your looping turn to right make sure you make it big enough so when you come to point 3 you have at least a 50 yard straight stretch BEFORE crossing rollers. You want to make sure you have a long enough straight run into the douple up to allow the boat to get back on set speed, get the wake firm again, and give the rider enough time to line it up. Generally, the longer the straight stretch before hitting roller the better. Also make sure you head toward the rollers in the middle of the straight at point 2 that made the rollers. If you head for the area near the initial turn (point 4), the rollers will be small and washy. The angle (X) is up to rider but should generally be between 60 degrees (open) and 90 degrees (closed). The more open the DUP the easier they are to hit but are less peaky. Closed DUps take more timing but thats where the serious meat is. I like mine closed or slightly open (80 - 90 degrees).
