I have never shot the QAD, but I currently shoot the NAP smart rest and love it. I know NAP makes a couple different drop aways, the smartrest, the scissor rest, and the QT 4000 (I think). A lot of the posse shoot one of the NAP fall aways and have really good luck with them. I have shot the Schaffer as well, it's a good rest but it's also about $120. Good luck with your hunt.
If the basic criteria for a vampire is a living entity that sucks the life out of you in order to sustain itself, then I know a few. They tend to hide out in Washington, DC.
