HI this is the update made earlier about using 8 strand Dyneema fishing line.(Ebay) made set of lines using 90lb line.
Use with Prism Quantum Pro in light to medium winds.Performed well with no stretch. 4 hours in total so far.
Because it seems a lot of retailers are going over to power kiting + finding lightweight sets are much harder to find. Manufacture of your own sets is one option.
I used different colours (used same colour was able to get sleeving in) add also cost of 100m for around £4.80. Complete set 25m sleeved less than £5, recommend make your own give it a try + if not happy with results. Have plenty of spare string for other use.
