IMO the function of the CORE Sensor (or ESP) bar is much better and works great for me. The lines unspin automatically when you pull down on the bar after a rotation or kite loop - no leash tangling, no depower line tangling, no fifth line tangling.
just an fyi: The only downside I can think of is that the 2 center/depower lines going thru the bar need to be replaced periodically but it's worth it. I think I can r&r the lines myself for around $15. If you wax the dyneema regularly the lines will last longer (50+ sessions?).
Hey Roberto, I cannot seem to find a video that shows how the release end of the chickenloop is attached to the release... Do you have a picture of that? Otherwise it looks pretty nice!
It's a simple hinged short pin that feeds into an eye spliced into the end of the chickenloop. The material they cover the loop with is very stiff and springs open when released. It's a new take on an old idea.
Drawings showing it's function and reassembly can be found on pages 8 and 9 of it's manual. http://corekites.com/sites/default/files/manuals/CORE_Sensor_Handbuch_Manual.pdf
The bar is very light, clean, and simple. Both the swivel feature and release work very well even in my powder fine sand. The trim cleat is easy to use too.
