We use LaserPro Gold spectra flying lines exclusively. We highly recommend LaserPro Gold spectra flying lines due to low stretch and high feedback for greatest flying pleasure. LaserPro Gold is also the recommended choice for top fliers in kite competitions worldwide.
We are currently evaluating Shanti Skybond lines for quad-line team flying. Our initial impression is that while Skybond is as slippery as LaserPro Gold, it does exhibit a tendency to stretch during flying. Response can seem more “spongy”, with a less direct connection to the kite than LaserPro Gold. In high winds, this might manifest as a vibration done the line with the kite is held in a hover. This is based purely on our experience, your mileage may vary!
