I have found 2 sources for Q-Powerline that seem to be the least expensive.

$130 = no shipping in US if ground shipping.

http://www.californiakiteboarding.biz/i ... rLine.html
$120 + $13 ground shipping.

I need 3 - 500ft rolls, so i want to make sure I am not missing a better source.

Does anyone have a less expensive source for ~1500ft of Q-Powerline?

for the QPOWERLINES 300lbs-1000'Roll:

I guess 300lb strength is OK for back lines but really recommend 600lb strength for front lines

I paid USD 130 for my 500ft 600lb roll, so these prices seem OK

Thx for the reconnaissance Sarc,

Xtremebigair did have the 600lb for 130 with free shipping. Just for the effort of posting here I think I will go to them.

Power line sports is the web site for the actual manufacturer of q-powerline, you'll see their sticker on the spool when you purchase it from any retailer. Some retailers will reduce prices for different reasons so searching around you can find the odd deal. The other thing to keep in mind with the 600lb test there is the regular q-power and q power pro. The pro 600 is thinner and is closer in dia to the 300 lb but it does cost more (about 25-30% more)

The pro line is good stuff - your bar will feel like a lttle more pressure - because the spongyness is not in the lines anymore, though it rewards you with an instant steering response...

Just out of curiosity I though the pro lines were just a bit thinner - and not recommended by most unless you are racing?

Do you really feel difference between pro and normal?

thinner line is always going to be lighter and less drag. Not just for racing and especially if you are using a larger kite to get out in the lightest you can go, then drag is something to consider.

Hey sarc - you wouldnt recognise the difference on the 600 pro line, from memory - kite lines only load up to about 70 odd kgs at full power during real load tests on the water..
Kite lines are way over strength rated for sales marketing crap and thats about it ... I just got them to speed up the steering responce - the bonus is theyll last 5 years no worries.
Get sleeves put on them if you dont have pigtails on your kite also...

600 pound lines snap pretty easy when you do a kiteloop, 800 is better. Even tho q-powerline is rated 600 it seems to have the same strength as 800 pound 12 strand line.
