Hi Kiteflyer,
Yes, I've noticed HQ does not have a pdf for the Matrixx. You can download the Matrixx Manual here:

You will probably want to keep the front lines attached to knots closest to the bar. The Matrixx tends to fly better with a little trim pulled in
(especially when you are getting used to the kite), and that is effectively what these knots are doing.
If you find the kite moving slowly or back-stalling it means you are choking the kite and either need to push the bar forward or pull more trim in.
The 9m is a super fun kite though - hope you enjoy it!
