So I put the cross-over bar on my 3m Brooza on Sunday. Setting the brakes is a little more touchy on this size but I found the sweet spot. There was almost no wind. Relaunching was even more difficult with the bar in this condition. The Brooza generally holds back inflating so is difficult with handles + no wind to launch as well. I think there is a little loss of control but not enough I won't keep it on.
The second test passed. I passed it to a total nube and he took to it right away flying kite loops and down loops instinctively within minutes.
So far I give it an A- .

If you want to launch in really low winds sometimes you've got to grab the power line leads off the bar and give them a yank, once the kite's off the ground and moving then grab hold of the bar, You'll want to do this long before the kite's finished filling. I've got to do that to get the 9m Buster off the ground, should work on the smaller kites as well.

YUP,
That's what I found worked best + trying to get it to fly fast across the window right away.
It's very do-able just a bit more clumsy than with other large opening, multi-vent trainers or with handles. Relaunch was the only thing that the nube didn't take to right away but he would have gotten it with more of a trainer. I'm not about to sacrifice the performance I need from a 3 just because I like to introduce folks to the sport. Besides, then they appreciate there trainer more when they buy one !
