It would be beneficial to know how the lines are set up for different brands. That way you change based on availability/price or quality, regardless of you brand kite. Can you help me with your brand?
It would be great if all brands just decided to make the lines equal between back and front lines. Today it is hard to find any info about the relation between them.
Lines I already know are exactly same in front and back:
Ozone (all years)
Slingshot
RRD
Naish
Ocean Rodeo
Cabrinha untill 2008 (verify please?)
Lines that are NOT the same in front and back:
Cabrinha 2010 (how about 2009?)
PS. It is ONLY the length of the actual lines, and the relation between front and back. Its easy to check .Stretch out the flying lines (the approx 20m lines) next to each other and see if they are same length by where they are tied to the leaders on the bar. Its easy and takes a second if you are two.
(Editing as we go, thanks guys.)
