I tried the bar with a Liquid force (old kite, about 2008) and although it flew, it felt like the back lines were far too long even when adjusted to the shortest setting. She just didn't want to turn without a massive amount of movement.
sounds like you were using a liquid force kite like the 2007 havoc designed for a 2:1 pulley bar. No modern kite requires a pulley bar.
Your choice of 2014 kites is limited to what whabbits said. naish, cabrinha, slingshot, liquid force, ozone, (and north in 2015), best, wainman have all switched from mini-5th to single center flagging kites
if you want more flexibility in kite choice you are going to have to upgrade your control bar. Otherwise . . . I guess just buy another ocean rodeo if you like their kites.
