Ragzilla:
1 / Did you buy your Cabrinha bar new? What year bar is it?
2 / What kite are you trying to fly it on? (Some kites shouldn't be flown with that configuration. A North Evo for example which is designed on a bar with a "high V" not a low V connecting to the top of the depower strap.)
3 / How much longer are your centre lines?
The Overdrive bar, particularly the 1X is defiantly leading the way as far as control systems go.
I'd be interested in hear your definition of "It sux".

Simple tuning can make your gear work quiet efficiently.
At lot of Kiters have been buying the latest overdrive for many different models, Gaastra Sparks, Naish Parks, Ozone C4's etc and all have great use of their bars.
I expect if you bought a second hand overdrive bar, that the front lines have stretched (which happens naturally overtime) you can easily adjust the line length using the adjustable pigtails. You want to get your lines connected to a fixed point (leash around a post for example and tie the pigtails to the clip), go and hold the bar end, fully powered under tension. All lines should be the same length.
