Please forgive me to have unvoluntary forgot the Hyperlink which is probably the easiest kite of all current foils.
Yes the shorter chord of race kites leads to more sensitivity to bridles movements. The worse being a small race kite (very little chord) . Moreover , Due to their competition target and endless seak of reducing drag, race kite often have small diameter briddles that are less stable over time and fatigue. Lastly the high aspect ratio of race kite are naturally less stable so require more accuracy on briddle length. So overall race kites will become less stable more rapidly (to be taken into account for second hand market)
