How To Avoid Line Burn (Because Raw Canopies Work Better) in Gear September 3, 2016 Yes you have to watch Spectra lines for temperature related friction damage! I have seen someone with Spectra lines land safely after kicking out of severe line twists. Then their buddy walked up yanked on one of the lines and it broke. The jumper got pissed at his friend for breaking his line but then he realized his friend was actually helping and might have save him from it breaking on him in the air. If you have Spectra lines always check them for damage after having line twists.
