Bought a3.5 XPS and loving it. What harness lines work well w the XPS. They are closer spaced than I'm
used to and the webbing holes are so strange? 
I use the Ozone Wing V2/3 harness line. Works perfectly. Just push the line through the webbing with one of the battens - also works very well.
I use the WIP 2.0 harness line on mine.
