This sliding creates a bit of inconvenience for a few reasons. First, it may be difficult to reach your control bar after you let it all the way out and your harness is sitting at your chest level. (This can be even dangerous since you can’t reach your steering wheel, so to speak. In this situation you may push the center line away and downwards with one hand and use another hand to grab the bar). Second, you will become unbalanced, since the attachment point of the kite will be shifted from your bellybutton (where the center of mass is) to your chest, and if the kite pulls, and pull it will, it will be easier for you to lose your balance and enter in an unwanted rotation, usually – face forward.
