Thinking of purchasing a Flexifoil 25m 330lb/220lb line set for my JoJo RM+ 5m. Just plann on using it to buggy/landboard.

Will this be strong enough?

...and is there a rule/guide to figure out appropriate line strength for a particular size of kite?

I use that strength all the time. It suits my uses just fine... I dont do any jumping with them, though...

should be fine. I weigh 145# and fly all my jojos on 300/150 and mostly on 25m lines except for my 2.5s which are on 30m lines just to slow them down a bit. Several other buggy folks near my also riding jojo fly in similar configurations and adjust the weight of the lines based on their own weight and length to prference (20 - 30m). Assuming you're not really heavy and not planning on doing crazy jumping that set will be more than sufficient, IMO.

I think they are plenty strong. You must see all those sets on eBay right now. I've bought a couple sets from the seller and you can't beat the price for those high quality Flexi linesets.

I'm not sure what the rule of thumb for line strength is though. Must have something to do with your weight and kite size, etc. I think that kitesurfing lines are much stronger than these, but of course much heavier as well.

Yep, been watching those linesets for the last few weeks. I've dealt with this seller before and had a good experience. What I've done in the past was just call them up and let them know that I saw that item sell for (best price I found) and they would match it. In this case it was $35!

Just wanted to make sure they would be strong enough. I'd like to fly with the lightest lines I can find without the risk of breakage.

Thanks for the replies...probably call them up on Mon and buy two sets.

three times your weight

covers safe accelr8d mass range with reasonable shock load tolerance

power /rider/drag /conditions cover completely to get the most from your gear and safety line for some is vital to rig safety and recovery / main line leash hook failure is a instant lost kite

I have flown this weight lines since day 1 and have never had one break or even fray- Excellent product!

I've flown 300 pound mains and 80-150 pound brakes for over 10 years with only one line break (caught it on a sharp object). Mostly I've kitesurfed with these lines.

For any of my light wind kites I prefer lighter than that maybe 200 pound mains and 50 pound brakes. Line drag eats up kite performance more than most people realize.

Most everyone puts to heavy of a line on their kites. Remeber double the cross section and you quadruple the drag. I don't know about any of ya'll but I can't hold on to something if it yanks at 300 pounds so I would rather a line break than my body, kite or harness.

Good luck-Scott

We measured my pull on a slalom waterski once at 850 lbs. Pros hit over 1200. That was really surprising how much of a load you can take when you are ready for it and send it. Some tough pressures to put your lines under would be scudding in soft sand, really putting the power on the lines while leaning back and digging in, or a water start would be a pretty tough job as well, especially with a harness to take the load. And one of those surprise 15 foot lifts would mulitiply the force of your weight like Phreerider said.

All I'm saying is I use 300 pound mains and 150 brakes on almost all my kites.

On the XXXL and 10.5 I use 300 mains and 50-80 pound brakes. Works like a charm.

I have used down to 200 pound mains on the big kites but didn't like the line because of stretch.

I use Quadrifoil Q-Powerline exclusively for my mains and Laser Pro Gold for brakes.
