Advanced riders who are doing carving 360s and working on riding backwinded will find it immensely easier to control the wing in those situations. Having hard handles to push against gives you a ton more control when backwinding instead of soft handles, which require you to push directly on the large diameter of the strut. When learning aerial maneuvers, like frontside 360s, advanced riders will find that the hard handles allow them to force the wing through the wind more effectively.
While soft handles are certainly a go-to for their cushy feel, convenient packability, and easy grip when using gloves in cold water, there are certainly a host of advantages to the hard handles on the new SlingWing V3 Hard Handle wing. The choice is yours!
