My lines are getting a bit stretched. So i want to get new ones for safety reasons. Im looking at this
http://www.coastalwindsports.com/servlet/the-705/Line-Set-4-...

1)which size should i get? (this is for a 15m synergy, and i only weight ~130lbs. small lines=less power? or is that longer lines?)
2)Which brand(manufactor) lines are best?

PS if you know of a cheaper website, feel free to post it ;-)

Those lines are for fixed bridle kites (power lines are not the same strength as brake lines). You need a quad set where all 4 lines are 500 - 600 pound strength.

usually the kite maker recommends a length but Angus at Coastal can help you with that.

We tend to ride 25 or 27m lines and 3m extensions on light wind days.

The Syn 15m came with 27m lines (i think, I can't really remember).

Small lines= a little less power across the window but slighty better power build up with snappier turning. Longer lines= more power across the window, slower response in steering, better ability to get to cleaner winds in tree lined areas.

I ride the Peter Lynn lines. They've had heavy use and have had zero issues. Q-Power lines are great as well but you're not going to get them for the price of those PL lines you looked at.:o

On my site links list on the left, go to Accessories, Line Sets, then 4-line Depower and you will end up here...

The Peter Lynn Line sets are first on the list. The 15 m arcs usually ship with 27 meter sets. I have HQ as well for just a few $$ less.

In the PL's I just have the 27's as I just shipped my last 25's but will re-stock shortly. Thanks for looking.

Big thanks for pointing that out B-roc!!
and thanks for the new link acampbell. $129 is more then i wanted to spend thou. Going to try to stretch out my old lines first :P
