I've been happy with my QAD UltraRest LD Pro Series for the past three years until this month when I started having trouble getting it to engage in the capture position. I roll the thumb wheel back 5 or 6 times with no luck. So, I torque it to the right while rolling it back and it engages...

I had my pro shop set my LD up for me and he set it up so that when it drops away it rests on the shelf. This seems to be working fine but I have seen others with it resting above their bows shelf. Is there a proper way to set it up or is it just personal perference?
