I used to keep hem rigged but don’t do it anymore.
Why Rigged:
Takes less time to unroll and set up the kite before take off.
Why not: Takes more time and its little more difficult to roll and pack everything when its all connected. If you use this method you have to pack and put in the bag immediately otherwise it is a pain to handle the gear. Once in the bag it does not matter.
I don’t do it anymore. Not worth the trouble. Only saves a few minutes on rollup.
A tip for setup time: Connect the lines to the kite before you unroll them from the bar. When you untangle the lines, do it in two steps. First two outer lines, then two inner lines. You may have to walk twice up and down the lines, but this is a very simple process that never creates the mega tangles that I always see on the beach and the time is very predictable.
On packing, roll the lines when they are still connected to the kite, and disconnect only at the end. Don’t disconnect the lines before rolling. It will keep them straight on the bar and also off the bar next session.
This IMO makes leaving the kite connected to the bar not necessary anymore.
Anyway walking 80 feet x 2 never hurt anyone
