If it is newtech, i would personally not fly it. I have a 3.5 ballistic and i have nothing but complaints with it. Of course i don't know about the
4-line thunder foils. I have flown the 2 line ones and they are ok.
Oh and i had the same problem with the ballistic line sets. They were completely out of whack.
