The only niggle I have is the bar ends are a bit soft. On the demo kite I used the bar ends had bent down and would hardly hold the lines on during winding and unwinding.
The loops would fall off and I would have to deal with tangles of varying levels of severity. It's not too bad but I haven't had a line tangle of any kind for years.
I guess if you own the kite and you are careful you can avoid crushing the bar ends but it's still a little annoying on an otherwise fine product.
If you have ever put your bar through the front of your surfboard
you will be happy for the soft bar ends
