I'm looking at a new rest for the Carbon Cure. Right now at the top of my list is the QAD HDX. Also on the list is the Rip Cord Code Red and Trophy Taker Smackdown Pro. My question is if one system is better than the other? If both cable activated rests have a lock feature, does it matter if the rest works off the cable vs. the limb? Any advice on these two or if there's another I should check out I'm open to suggestions. Thanks.
