Have used this new bar for a couple of sessions now and it works great.
Above the bar depower with adjustable travel/throw.
Lines are 20m with extensions thrown in and I prefer to ride 20s anyway.
Bar grip is comfortable and looks durable, only time will tell.
Quick release/safety works well, I trialled the safety features on the beach to get familiar with it.
I like the way you can put the Chicken loop through the double ring safety to give you a suicide style safety which I prefer when riding.
I like the extra resistance/stopper and will be putting mine on permanently, the safety line goes through it so you cant/wont loose it. I trialled it for a session with and without it.
I have the Zeeko Notus 3's with this bar and love the kites and the bar.
The new bar is good, I would like to Demo the new Notus 4 with one

Demo one
You might be pleasantly surprised
