Rob, did you ever got that Power Sled 24 found or returned ?
Hyzakite, question : what kind of parafoil 5 are you referring to ?
GammoRay is correct
I fly power kites (inland, no buggy yet) ... you do need more than #300 lines ... I weight 180lbs and my Rhombus Anum 7.2m did pick me up and carrying me here and there at 12mph+ and Ozone 3m at 22+mph ... I got very lucky that I wasn't in the air when my handles's leader lines broke twice (each handle, one that day and other another day) ... I replaced it with true 550 paracord and do check lines/handles once a month
if I ever planning to stay in the air longer than 15 seconds ... I will definitely need #500 lines or more to ensure it won't drop me free falling and double the strength on the handle's leader lines
No, I don't use control/turbo bar (not made for these 2 kites I have) ... I use 2 handles
