There are a few tricks to set up that rest with the SC Pat. Non are that great IMO. It seem the bow wants to kick the nock down on release, so you need more support from the rest. The rest needs raise at the last 3 to 4 inches of draw. This will stabilize the arrow and allow time for the rest to drop.
You cant tie to the cord to the down cable, because it will not allow the rest to come up soon enough -(to much pressure on the cable-cam). Unless you add a spring to the cord. The spring will provide enough pressure to lift the rest and not kill the harness. This is how I have mine set up - and it works well.
Bowtech suggests attaching to the cable slide. You will find that to get the rest up soon enough you will add quite a bit of pressure to the slide. Kind of turns it into a legacy

. I got close to eliminating, fletching contact this way - but could not get it 100% free. I feel setting it up this way will ruin a harness rather quickly.
I tried for days to get it to work according to both TT and bowtech - my spring idea is the only way it worked for me.
Another problem with the Patriot is the cable slide - bad design IMO. there is almost NO fletching clearance. Buy the sims teflon slide. It pulls the strings much closer to the rod - and will allow you some room to index nocks.
If you get it to work let us know.
