Just curious. Could you use an IDS bar with the kite or is the race bar significantly different? Besides the 24/27m lines and the cleat de-power what is the difference?
Short answer is no.
Longer answer, the safety system on the kite is different, so as you could probably use any bar with equal line length, the ids safety system wouldn't work, so if you punched out of the kite, not sure what it would do. The velocity bar is a single line flagging safety system.
Has anyone tried an IDS bar on a kite that normally uses a single line flagging system?
