I don't own the PR but I have shortened the lines on my SAB foil Ala. Rather than cutting and splicing I have shortened each leader line by 8 inches via figure 8 knots as per photos below. On water testing showed a huge improvement in my ability to pack down the wing without effecting the power or flying performance. I also thought that the knots and doubled up lines would cause tangling issues but so far so good. Maybe one day I'll end up splicing all of the lines but at this stage I don't see the point.
