Had mine in 40 mph on 100' x 150# Prism dyneema. Only went center window a few times and 40 is the max for me.More time in the center and I think the lines would have failed. Don't have a tail for it yet but it's the only kite I want to put one on. On 65' lines I doubt I could handle it well without one. Started to get some dyneema 220# lines a few times but for 30+ winds think I need 120'x170# Shanti. That's not cheap.There are some 250# x 98' dyneema with winder and straps on Ebay for $6.99 from China. Haven't got them because of the length. From what I've gathered 170# Shanti is stronger than 220# dyneema.In high winds not sure if the high end lines justify their cost but that's where I'm heading. I've got a Mind trick vented that got hit by a 40 mph wind on 150# x 100' LPC and didn't sustain any damage. Don't intend to fly it over 30 but wind happens.The Hawk has pert near twice the pull as the Mind Trick in 30. Maybe for $14.00 I should just splice 2 dyneema sets together and see what 199' feels like LOL.
I too own a Delta Hawk and a Hypnotist. The Delta Hawk should be fine on the #150 lines. I have flown mine in excess of 25 mph with the line set from my Hypnotist. You can always fly to the edge of the wind window when it’s gusting hard just to be safe. Add a tail to slow it down and put on a show. I was wailing on my Delta Hawk last week in winds above 30 mph with #220x65’ lines and a 75’ tube tail. It’s a great kite to have in the bag for days when winds would shred more mortal kites. Worse case scenario is you break some lines and have to upgrade yourself to some laser pro gold line. Get out there and fly it with intent! Sent from my iPhone using KiteLife mobile app
