While all the wave shapers made the Malibu Sunsetter surfable, they are all different. Moving the position and angle of each has a different effect on the wave. The bigger units, such as The Wakesurf Shaper and Roswell Deflector, perform better mounted closer to the transom. Others such as the Delta 2.0 and XLR8 seem to do better farther forward. All of this depends on your specific boat—and where these can be mounted based on design characteristics on the side of the boat.
Your board matters, especially on smaller, less powerful waves. A bigger board with more volume will be easier to surf and get into the pocket of the wave.
Each of the devices is relatively easy to mount, thanks to their suction cups—some took more effort than others—and all of them float. This makes changing sides or adjusting positions hassle-free.
