Can't see any good reason wht one would adjust the bar throw more than once...
I am not sure but i think they have a stopper ball as an option. You can buy it seperatly.

Jackc this short vid from the guys at KSW may help explain..

Finally here is a small vid on the UNI bar!

I have used the Unibar for many sessions now, with a new 9m triggger and the 2012 12m trigger, fat lady. Its a sweet set up! The 2012 kites fly super tight and turn fast. Not missing the strap sheeter at all or that bulge at the center of the old bar. Its amazing how a little rectagular shaping brings the comfort and control levels up. Blade builds a kick ass kite, this new bar lets you feel that power in a manner that is truley outstanding. I like how the leash pulls the slack out of the mini 5th. Keeps the sheeting area organized. The center line spreader is rotating smoothly and looping is funner. A big hats off to the one came up with the flying line. Those center lines are beefy as heck and they all interact beautifully, easy to unwind when you set up and a lot less prone to tangles than symetrcal line sets IMO. The long stiff dick is rock solid and you stay totally connected.
I really like the Unibar the the thing feels like a fformula race car wheel in your hands....you just have to push that proggression harder when you are riding!

Great video Jinx!
