One thing I suggest to people who are starting out and trying to save money is to get a new bar and lines with mini 5th line
mini 5th will not flag kites with short brides (ozone cat, slingshot z, rally). You can look at a kite and tell if it will flag mini-5th the bridles are long and have pulleys. When you throw the bar all the way out on a z or cat or any c kite they will fly on the front lines instead of depowering like you expected.
Could be dangerous if you try to fly a ozone cat on a cabrinha bar and expect the kite to fall into the U position that cabs normally do if you pull QR1 and now your kite is still in the sky pulling you but the bar far away and about the only thing you can do is ditch the kite with QR2.
A fully single line center flagging bar like the slingshot bar will however fully flag any kind of kite. Liquid force by the way flags to a single center line, but if you look at the kite, you'll notice it has the long bridle and pulleys that will let it flag properly on a cabrinha bar --- though there is also the issue of the "high Y".
It's really difficult for a newbie to know all this stuff when they start out.
