Any insights from the technically minded into the importance of the weight of the bar (and lines) on performance of a kite specially in light wind (below 10 knots)?
I see racers using very simple light weight carbon bars so I assume it makes a difference. But how much?
If a light wind tube kite shaves a few hundred grams off the weight of a 'normal' kite, how much difference would a few hundred grams off the bar make?
It is of "mental" importance, A LOT
But the weight doesnt matter really, in terms of performance, neglectable compared to the total weight.
Four strong thick lines only weighs about 100 grams (170 if 30 m lines), and you can only reduce it by a factor 4 to 5.
I use 0,83 mm frontlines and 0,6 mm rearlines, 30 m long + bridles, for my marginal wind foilkite, and a superlight carbonbar.
As opposed to the 1.5 to 2 mm lines when using "strong" kitelines.
The weight is one thing of course, but only mentally.
But I believe the thinner lines makes a difference in terms of drag when you fly and loop the kite with longer lines and 5 knots of wind - how much I dont know, but thats the reason why I have pinched "everything" out of it.
Also when possible only shorts or shorty and a light harness, no shoes no helmet etc - everything helps.
Apart from a superlight big special lightwind board, a light carbon foil, a higher AR bigger wing.
Then I get as low as I can in terms of lowend
Even for racers, the more "direct" feel is mentally IMO, but plays a big role.
Lines get softer if thinner, thus here it can be better with thicker lines for racing where you want direct response to accelerate in gust instead of spilling, so the opposite desire than for marginal wind and drag.
