I've been playing with tuning line lengths lately and have settled on 3/4-1" shorter steering lines than "stock". What I mean is when the lines are hooked on my nail-in-a-mango tree and I pull back on the chicken loop and bar the original spec is for the bar to be just barely touching the chicken loop assembly. What I prefer is when the outer lines are a little shorter and the bar stops almost an inch in front. Any shorter and it's too easy to back stall the kite and I have to use some depower more often in gusts. At the stock setting I miss being able to get a little more pull, especially during jumps.
I've also started making the left line a tiny bit shorter so the bar is very slightly cocked. I'm goofy foot and this feels better for making a down stroke on my toeside without being enough to notice when up stroking or riding heelside.
Anyone else also run their lines so the kite can be "over-powered".
I only use Naish 20m BTB bars (easy to reach depower while riding toeside) and Slash or Pivot kites 6,7,8m. Occassionally 10 or 12m with 24m lines.
