Reading a few things online where people say the new Dyneema Sk99 lines makes the kite much more responsive versus the older and much weaker Sk75 Dyneema lines. Has anyone noticed this or made some lines of Dyneema SK99 recently ? (ideally 1.6mm)
Just found a great new Drneema for those interested - "Southern Ropes - Stealth Fibre GP-12", they claim a breaking strain of 880kg on the 2mm Dyneema which is extremely high breaking load for that diameter. I have ordered some for my single front line section on a Naish Torch bar (2014), the central black line which is 11m long.
Looking for 1.6mm flying lines, the Sk99 seems the best by a long way.
All my clients immediately feel the difference when switching to a SK99 set of lines.
I use 500kg front and 300kg backlines, 1.7 and 1.1mm. Although some megaloop/stormkiters use 500kg for all lines as they feel more rigid and tangle less in 7bft+ winds.
For racing I use 300kg sk99 and 170kg sk90. It even holds when boosting in stronger winds.
I don't like the 0.8mm Liros 8-strand 160kg sk99 line. Harder to splice, rough outside weave and I couldn't get it above 130kg breaking strength on the splice while all other lines easily exceed their given breaking strength on my rig.
"Downside" to Sk99 is that it is so thin that you must use pigtails or Dyneema sleeves, it cuts right through the polyester sleeves when approaching half the breaking strength.
