Plan to add litte gismo to use my Ozone bar with my Bandit when I go overseas (so I carry only one bar with me). 2019 Bandit bar has 24m lines with the center lines split 4.25m away from the chicken loop (depower set to full power - longest possible setting).

For best performance aim for 20m of lines after the center line split. Not exact science, but don't think you want to be off by more than couple meters

f-one changed to single line flagout in 2018? while others did it 4 years before? Shows their lack of regard for safety.

There will be always different views on this.

One can alway argue that if on a 4 line kite which has a single line flag out, that line was to snap, you'd end up in deep **** whereas with safety on both front line, you'd still have the second one to save your arse.

I had F-one before and after the change. Never had to use it but you are right, single line is more efficient (unless it snaps when you need it...)

Bottom line is if you really care about safety, get a kite with a fifth line....



Back to OP's question: it is recommended to fly the bandit with a high V (around 4m as Swavek mentioned). If the North trust bar has a high V around 4m then it will work fine.
Mind that The Bandit connectors are 4 x pig tails and you will find that most other brands have a combination of 2 x lark heads and 2 x pig tails.
And easy solution would be to buy extra connectors to match whatever is on the bar that you are gonna use if that makes sense.
