For a dual line set?
Of course John, for a dual line set. For SUL kites like Skyburner Pro Dancer, Spectre XUL, Big Easy Kites M2 and some others, by very low winds.
Iím also using 2 Kg Ė> 4 Kg (9 lb) Spectra lines for small kites framed with 1.5 mm / 2 mm rods. But with lines less than 20 meters.
I could understand small fighters at that line weight, but that's about all.
Fighters kites are not using Spectra/Dyneema lines.
Back in the day we used to carry Laser Pro Gold 'Micro Line" that came in 10, 20 and 30 pound weight.
Haven't seen that in years though ... so basically no help here
Thatís exactly what Iím looking for. 2 or 3 years ago, GWTW had some 30 lb Laser Pro rolls for sale. Laser Pro Gold is still available now in 50 lb (23 Kg) but not less.
Best bet is dyneema/spectra fishing lines.
I know Andre but fishing lines are more elastic than Laser Pro.
