The guy that bought my used 2010 Bandit III is still using the same lines.
The guy that bought my used 2009 Torch is also using the same lines.

It looks like loaded the center lines goes up to 64 kg and the steering lines are about 10.5 kg load each.

I didn't see this guy properly load his board, send the kite or do a proper jump....ramping off waves doesn't count
Forces would be significantly higher than his body weight. (2-3) times at minimum Regardless much less than 600 or 800 lbs/line

ALL that strength isn't needed. but you need a significant factor of safety to survive in the real world and not break when
a) punch holes in them to sewing on sleeved ends.
b)when you tie knots in them (like attaching them to the kite.)
c) when you do kite loops or backrolls and fly with your line twisted for a little bit and the chafe like crazy.
d) fill up with dirt and abrade.
e) get small cuts from stuff on the beach
f) degrade in the sun.
g) they fray and lose some strands

(all reasons to buy some Q power lines)

Typically ropes specifiy a "safe working load" which is usually about 1/10th or 1/15th of the actual breaking strength depending who you talk to. To account for knots, damage, degradation etc

Back to the original poster grype, most companies have good lines. the only shit lines I've encountered were liquid force circa 2007-2008. busted 2 sets of these no warning other than the PING noise in the air. Friends had similar results.

^ This. I have more than 50 sessions now on my 2013 Lithium 14 + Analog Bar and the lines haven't stretched AT ALL.

Compared to my 2010 Best RedLine, where the massive grunt of my Kahoonas (V1 and V2) made the steering lines stretch unevenly starting from the third session, it's a blast.
Don't get me wrong, I love my Kahoonas and I feel very safe with the RedLine, but I can really see the difference in the quality of the lines.
